Buffalo Soldiers Trail

In early 1911, geologist named Thomas A Jaggar convinced Frank A Perret, a world-famous American volcanologist he had met on Vesuvius Volcano in Italy, to travel to Hawai‘i to begin the observations of Kīlauea’s volcanic activity.

From July to October 1911, Perret conducted experiments and documented the lava lake activity within Kïlauea’s Halema‘uma‘u Crater, paving the way for Jaggar to pursue his life’s goal of using multiple scientific approaches and all available tools for the observation and measurement of volcanoes and earthquakes.

In 1911, the first scientific laboratory at Kilauea consisted of a crude wooden shack constructed on the edge of Halema‘uma‘u that was called the Technology Station. The next year saw the construction by Jaggar of the Hawaiian Volcano Observatory.

When Jaggar came to the Islands, he joined the efforts of George Lycurgus (operator of the Volcano House) and newspaperman Lorrin Andrews Thurston who were working to have the Mauna Loa and Kilauea Volcanoes area made into a National Park.

Jaggar had tried to lead several expeditions to the top of Mauna Loa in 1914 but was unsuccessful due to the elevation (13,678 feet) and the harsh conditions: rough lava, violent winds, noxious fumes, shifting weather, extreme temperatures and a lack of shelter, water and food. (Takara)

In September 1915, Jaggar, Thurston and a US Army representative conducted a survey to determine a route for a trail up Mauna Loa.

The following month, a local paper noted, “Soldiers Building Mountain Trail. Negro soldiers of the Twenty-fifth Infantry to the number of 150 are at work constructing a trail from near the Volcano House to the summit of Mauna Loa.”

“It is estimated that three or four weeks will be devoted to this work. The soldiers are doing the work as a part of their vacation exercises.” (Maui News, October 29, 1915)

Immediately after the Civil War and the abolition of slavery, many African Americans found themselves newly freed from bondage. In 1866, congress created four military regiments made up of Black troops, the 9th and 10th Cavalry and the 24th and 25th Infantry – they were known colloquially as the Buffalo Soldiers. (NPS)

“Although Native Americans bestowed the name upon the troopers, there are differing accounts as to the reason. One account suggests the name was acquired during the 1871 campaign against the Comanches, when Indians referred to the cavalrymen as “Buffalo Soldiers” because of their rugged and tireless marching.”

“Other accounts state that Native Americans bestowed the nickname on the black troopers because they believed the hair of the black cavalrymen resembled the hair of the buffalo.”

“Another suggests that the name was given because of the buffalo-hide coats worn by the soldiers in cold weather. The troopers took the nickname as a sign of respect from Native Americans, who held great reverence for the buffalo, and eventually the Tenth Cavalry adopted the buffalo as part of its regimental crest.” (Plante)

“The generous cooperation of the United States Army has made the trail to the top of Mauna Loa and the rest houses at the top and midway thereto a certainty.” (Hawaiian Gazette, Sep 24, 1915)

“The overpowering feature of the landscape, however, is the immediate foreground to the north and east. The trail up to Red Crater is through ordinary and rather monotonous lava flows; but from the top of the hill there literally bursts into view a scene of most violent volcanic activity that I have seen anywhere.”

“It is similar to the interior of Haleakala crater; and the top of Hualalai, but while those are old and faded, this is fiery red and inky black.” (Hawaiian Gazette, Nov 11, 1915)

“During the past summer [in 1915] the promotion committee and Research Association formulated and presented its plan to the authorities of the County of Hawaii and the newly created Hawaii Publicity Committee …”

“… proposing that these two organizations with the assistance of private subscriptions should furnish the money necessary for the material involved, the work to be done by the county prisoners.”

“The county authorities and the publicity committee each agreed to contribute $500 toward the enterprise. Then the Governor came in with a contribution of $500 from the contingent fund and private subscriptions have been received in excess of $1000.”

“No decision had been arrived at concerning the availability of the county prisoners, however.” (Hawaiian Gazette, Sep 24, 1915) (The practice in Hawai‘i and elsewhere was to use prison labor for public works projects, including road building.)

(Later Territorial law stated, “All prisoners sentenced to imprisonment at hard labor shall be constantly employed for the public benefit, on public roads or other public works or other wise, as the high sheriff, with the approval and subject to the control of the board of prison directors, may deem best.”)

Then the military offered aid in the form of a “tentative proposition that, if transportation was furnished from Honolulu to Hilo and return, Company E of the Twenty-fifth Infantry, consisting of between 140 and 150 men would volunteer to go to Volcano, and do the work of building the trail and erecting the rest houses without further expense to the promoters or enterprise.” (Hawaiian Gazette, Sep 24, 1915)

Building the Buffalo Soldiers Trail (now called Mauna Loa Trail) from the 4,000-ft. summit of Kīlauea to the 13,677-ft. summit of Mauna Loa was no easy task. (NPS)

“The soldiers are constructing a trial three feet wide across the a-a, crushing it down with twelve pound hammers, filling in hollow, cutting down ridges and putting on a finish of fine a-a and earth, quarried along the line or parked in gunny sacks, carried on the men’s backs – in some places being carried as far as a quarter of a mile.”

“The Mauna Loa trail and rest house project is making steady and substantial progress. It must be remembered that it is through a section of territory never before inspected, much less traveled over, except the lower portion thereof, and that only by a few surveyors, cattle men and catchers of wild goats.”

“No one wants to run away with the idea that the job which the men of Company E of the Twenty-fifth Infantry have volunteered to do is all picnic. They are having a picnic all right; but incidentally they are doing a lot of good hard work in a pure pro bono publico spirit.” (Hawaiian Gazette, Nov 11, 1915)

The Buffalo Soldiers built the 18-mile trail to the summit of Mauna Loa. They also built the ten-man Red Hill Cabin and a twelve-horse stable, so scientists could spend extended periods of time studying the volcano.

“[D]uring the period of 1915 to 1921, the trail was managed and maintained by a loose consortium consisting of Hawaii Volcano Research Association, Lorrin Thurston, Hilo businessmen, and Thomas Jaggar, then it was managed by the National Park Service.” (Tuggle)

Between 1930 and 1932, the National Park carried out major improvements and realignments of the Mauna Loa Trail to fall completely within the park boundary. Over the past century, the evolving needs of the National Park and changes in available

technology have resulted in ongoing modifications to the physical footprint of the trail.

The uppermost portion of the original trail footprint has been nearly obliterated since the 1970s by a series of large lava flows in 1975, 1984, and 1985. (Tuggle) (The inspiration and sources to information here came primarily from a study by Myra Tomonari-Tuggle.)

St Peter’s Chapel

“There are a few, very small fishing villages, Alae, Alika and Papa, which are reached by poor trails from the mauka road. It is necessary to travel from Hookena mauka to the main road to Papa, and thence by either road or trail to Hoopuloa, the last steamship landing in Kona.”

“This is another village which is dwindling in population, only a few Hawaiians and a couple of Chinese storekeepers remaining. A fair road leads across a barren a-a flow to Miloli‘i, the largest and best specimen of an exclusively Hawaiian village on the Island, which is seldom visited.”

“It is splendidly situated by a sand beach, the sea coming right up to the yard wall, and is inhabited by a rather large population of Hawaiians, who prosper through the fishing which is almost phenomenally good…”

“This region is seldom visited. Its chief points of interest are the remains of a heiau, mauka of the Catholic church at Milolii, some fine papa konane at the south end of the same village a well preserved kuula (still used) where fishermen offer offerings of fruit to insure a good catch, by the beach south of Milolii, where the Honomalino Ranch fence crosses the trail; while all along the trail are smaller kuulas, and at many points the foundations of villages, where old implements may still be found.” (Kinney, 1913)

“Hoopuloa was one of the few typically Hawaiian villages remaining in Hawaii. It comprised of a cluster of 10 to 15 homes of old Hawaiian style and boasted a population of approximately 100 persons … The wharf was a port of call for the Inter-Island steamers”. (Honolulu Star Bulletin, April 19, 1926)

Then … “The number of earthquakes recorded for April [1926] was 671 (compared with monthly average of 52 for the preceding 3 months. … The maximum daily frequency of earthquakes in the 1926 eruption was on April 15 (86 shock), the first day of free-flowing flank eruption …” (Jaggar)

Edward G Wingate, USGS topographical engineer, was mapping the summit of Mauna Loa in 1926, changing campsites as the work progressed. On April 10 his camp was along the 11,400-foot elevation, well into the desolate upland above the Kau District.

An earthquake wakened the campers about 0145; as they drifted back to sleep, a further series of quakes had them sitting up, talking, and wondering. About 0330 Wingate braved the cold and wind; with a blanket wrapped around him, he went outside and stood bathed in reddish light. (USGS)

There was a brief summit eruption, followed by 14 days of eruption on the southwest rift zone. “About 3 am April 10 (1926,) glowing lava spouted along the upper 3 miles of cones and pits of the Mauna Loa rift belt, immediately south of Mokuʻāweoweo, the summit crater. … The actual beginning shown at Kilauea by seismographic tremor was 1:36 am, followed by two pronounced earthquakes.” (Jaggar)

For three days the HVO party surveyed the sources of the eruption; then they descended and moved into Kona District, where roads, houses, and other property were threatened by the flows. Wingate and his crew stayed behind. Much of the area already mapped was under fresh lava, and there was a lot of remapping to do. (USGS)

“A crack only 1 to 3 feet wide opened southward from a point tangent to the ease edge of the bottom of the south pit of Mokuʻāweoweo, vomited out pumiceous silvery pāhoehoe froth lava, and extended itself S.30^oW. past the next two pits and over the brow of the mountain down to an elevation of 12,400 feet.” (Jaggar)

“Fortunately the main gushing of this first phase ceased about 5 am the same forenoon, after flowing 5 hours. … (Then,) The vent crack was splitting itself open downhill. The source pāhoehoe changed itself by stirring into scoriaceous aa half a mile from the vents”. (Jaggar)

“When it got close to the upland of Hoʻopuloa, the flow of lava separated into two, and one of the flows went straight for the village of Hoʻopuloa and the harbor, and the second flow went towards the village of Miloliʻi.” (Hoku o Hawaii, April 20, 1926)

“(T)he Honomalino flow to the west finally dominated, … This was also aa. … It crossed the belt road at 12:22 pm April 16, 3 miles above Hoʻopuloa village.” (Jaggar)

On April 16, Jaggar scratched marks about a foot apart across the rutted, gravel road (the only road) between the Kona and Kau Districts. A lava flow was approaching, and Jaggar wanted to measure the flow’s speed as it crossed the road.

St Peter’s Chapel, sometimes referred to as Ho‘opuloa Catholic Church, was on the makai side of the road. Perhaps a hundred people were waiting around the Hoʻopuloa Church, on the uphill side of the road, and at the Kana‘ana house opposite, on the downhill side of the road.

They had seen and heard the flow, 15-20 feet high and more than 500 feet wide, as it moved through the forest uphill. When it neared the road, people who lived on the Kona side of the flow moved off to the north, and those who lived on the Ka‘u side moved to the south, so they could go home after the road was closed. (USGS)

Jaggar recorded that it reached the uphill, inland side of the road at 12:22 at an estimated speed of about 7 feet/minute; within two minutes the road was crossed. Jaggar and his assistant, HS Palmer, stayed on the Ka‘u side. (USGS) St Peter’s Chapel, sometimes referred to as Ho‘opuloa Catholic Church, was on the makai side of the road.

“The Catholic church, where many Hawaiians worshipped, was one of the first building to be destroyed in the flow which buried Hoopuloa.” (The Star, NZ, May 21, 1926)

“It is true that I saw the church destroyed by the lava tide, which moved onward with irrevocable majesty, entering the house of worship by way of the open front door.”

“Through the windows I observed the red mass proceed to the alter as the whole structure, capable of seating 20 worshipers, burst into flames.”

“Most dramatic of all was the moment when the slow moving red-hot deluge, pressed on by the mass of lava from the rear, tipped the church from its foundations and set it careening upon the molten river.”

“Straightaway, the bell, which hung in an open steeple, began ringing. It pealed above the roar of the flames and the grinding of the blazing substance surging onward.”

“A dozen doleful strokes of the iron tongue echoed farewell before it fell from the cross beam ringing its own requiem.” (Father Eugene Oehman, Honolulu Advertiser, July 31, 1932)

A memorial to the church was erected; the plaque on the monument reads “1926 Hoopuloa Catholic Church.” “Under the cross, 25 feet below the surface is all that remains of a small Catholic church, over which the lava flowed without a moment’s halt.” (Honolulu Advertiser, July 31, 1932)

“The fiery lava engulfed the harbor and village of Hoʻopuloa, and now they are but a heap of pāhoehoe lava.” (Hoku o Hawaii, April 20, 1926)

“Families of Ho‘opuloa were forced out of their homes by the flow, and many eventually settles in Miloli‘i on state land. The displace families remained on the land although they had no legal title to the property.” (Hawaii Tribune Herald, July 10, 1985)

In 1932, St. Peter’s Catholic Church at Miloli‘i was built by Father Steffen to replace an earlier St. Peterʻs destroyed by the 1926 lava flow. (PaaPonoMilolii)

In 1982, the State Legislature passed Act 62 which designated 52.6 acres of state land to be leased to the refugees and the descendants of the Ho‘opuloa lava flow.”

The Act also created the criteria by which people could qualify fo5 65-year leases” Initial implementation of the Act took place July 12, 1985 with the signing of 12 long-term leases for families living on the designated property. (Hawaii Tribune Herald, July 10, 1985)

Gardens of the World Highway

“In 1945 Governor Ingram Stainback requested that Director of Institutions, Thomas B. Vance, concentrate his efforts on developing self-supporting prison industries.”

“The industries established had to be almost entirely in noncompetitive fields and organized such that specific responsibilities, in the nature of long or short term contracts, could be given to the prisoners.”

“With that in mind, Kulani Prison Camp opened in 1945 as the successor to Waiakea Prison Camp, operated a lumbering enterprise producing logs and milled lumber of native hardwoods as materials to be processed and sold from Oahu Prison’s industrial area.” (Department of Institutions Summary 1939-1958)

The development of Kulani Camp and its means of access, the Stainback Highway, fell under the management of Vance. (Maly)

“Also established were agricultural, horticultural, and floricultural programs built around temperate zone crops, with the emphasis on crops not grown locally (apples, plums, dahlias, etc.).”

“Kulani … provided a reservoir of manpower for the construction of public roads on Hawaii …. – roads that would have been economically prohibitive if built under contract.” (Department of Institutions Summary 1939-1958)

Vance wanted to build a road to the top of Mauna Loa. (The reason Mr. Vance gave for choosing Mauna Loa was the resources of the Kulani area.)

A road like that didn’t command the funds necessary for ordinary people to do the job. Territorial law did not authorize appropriations for building roads by prison labor, but after some cajoling by Mr. Vance, the legislature allowed him to make labor available to nonprofit community service organizations.

In 1949, Vance went to the Lions Clubs of Hawaii and the Hilo Lions was specifically chartered to build a road to the summit of Mauna Loa. The Lions held their convention in Honolulu in the spring and came up with $300 for the project.

With this amount and other Lions Clubs’ money and some Mr. Vance had collected by selling small lava rocks from the slopes of Mauna Loa for a dollar apiece to anyone coming into his office.

He made nine miles of road above Kulani which became a show place. Contractors kept in contact to find out when a machine operator might be up for release so that they could hire him.

Funds were finally appropriated for building roads on most of the islands by Mr. Vance’s people. Actually, the inmates began to thin out with so many projects and civil service employees of the group, called instructors, not guards, did most of the work, helping with unemployment problems.

The US Secretary of Interior visited Hilo that year. Vance so enthralled him with another scheme he had that it was agreed to. This was the double idea of having short ski runs scrapped out on the lava fields up near the summit and having some of the “wayward boys” brought out of the institutions and given Park Service shirts and hats and have them act as ski guides and teachers when the snow came.

This, he said would restore a sense of purpose to these youths. The ski runs were just leveled off places at about 10,000 feet where one could use anything to slide on the snow like an old piece of roofing metal which was stacked for this purpose nearby. (Ellis)

In 1951, a weather station was set up by the Weather Bureau near the summit of Mauna Loa mountain on the island of Hawaii. An instrumented building was dedicated there as the Mauna Loa Observatory on December 12. (Ellis)

Also in 1951, members of the East Hawaiʻi business community approached Vance with a proposal meant to draw visitors to the Island of Hawaiʻi. The proposal was for the development of the “Gardens of the World Highway.”

As proposed, the highway would ascend the slopes of Mauna Loa, ending at the summit, near Mokuʻāweoweo. The idea was enthusiastically adopted by Vance, and supported by Governor Stainback. (Maly)

“When completed it will enable motorists to travel rapidly from a tropical wonderland through the projected Gardens of the World planned by the Hilo Women’s club, up to the 13,000 foot reaches of Mauna Loa into the atmosphere reminiscent of Lake Placid, NY.”

“Mr Vance said this road will serve two major purposes, each of which encompasses other secondary values. Running to the rim of Mokuaweoweo crater, it will, first of all, open up a winter sports area for the territory. From this would emerge an advertising and promotional value that would add to Hawaii’s fame as a resort area.”

“Ice skaters in grass skirts or snowball fights amid the palms are just fantastic enough to grip the public imagination.”

“But even though they sound unreal, they are in the process of coming to reality.”

“Not that such frivolous activities would in themselves justify the road now being pushed up the side of Mauna Loa on the Big Island.”

“But they will be a couple of the many by-products of the project to heighten tourist interest in the territory.”

“This was the substance if the report by Thomas B Vance, director of territorial institutions, yesterday. Mr Vance appeared before the territorial affairs committee of the Honolulu Chamber of Commerce.” (Star-bulletin, October 18, 1951)

“A garden of the world, to stretch from Hilo to the summit of Mauna Loa, was discussed at the business meeting of the Hilo Woman’s club yesterday afternoon at YWCA activities building.”

“The highly imaginative plan with its practical basis as a big boost to the tourist industry was endorsed by the Woman’s club.”

“A group of citizens, including Mrs Leo Lycurgus, chairman of the Woman’s club outdoor committee, Thomas Vance, head of the department of institutions, and persons interested in both the Kulani project and the beautification of the Hilo area had met informally at Hilo hotel and formulated the idea, which was written for the presentation to the Woman’s club and will be sent to all other civic groups here.”

“The garden, according to the plan, would follow the path the new Mauna Loa highway. Since the climate varies as the highway progresses up the mountain, the plan pointed out that ‘flowers from Argentine to the Arctic could flourish in the various sections of the area.’”

“The soon-to-be-completed Hilo waterfront area would be the base of the world garden while sectors near Hilo and the Panaewa forest reserve could be used for the long-talked-about botanical garden of island flowers.”

“Next would come an area of tropical trees, the flowering plumeria, the purple-budded jacquaranda, and the red African tulip. All these would be interspersed with the lush native tropical jungles which now border the highway. Flowers from temperate and cold climates would be planted at their proper growing levels.”

“Mrs. Lycurgus, who presented the plan to the Woman’s club, explained that ‘while it is a visionary idea which will take years of work before it can be completely realized, the plan for a garden of the world on the Big Island is a possibility.’”

“She said that the labor in planting and upkeep could be partially done by utilizing the prisoners at Kulani. In addition, she pointed out that the Hawaii Vocational school is beginning landscape courses and the training of professional work and set up a new profession on the island.”

“‘The big thing is the impetus such a garden would give us to the tourist industry,” Mrs Lycurgus declared.”

“‘People have gone to visit beautiful gardens all over the world. A great deal of interest would be generated by a long drive in which would be combined all the types of gardens throughout the world.’”

“‘We’ve always complained about the rains of Hilo,’ she continued. ‘Yet this idea offers us an opportunity to harness the fain for our benefit, to make it produce some of the world’s best flowers in the world’s most varied and all-inclusive garden.’” (Hawaii Tribune Herald, March 15, 1951)

Nina Lycurgus subsequently stated that the project was the work of many people and organization, and should not be solely attributed to her.

“I was not the originator of this wonderful Mauna Loa project. For many years the women of Hilo. Always interested in plans for beautifying their city, have supported and sponsored projects for beautification, and this idea for the Mauna Loa gardens is the final result to which many people and organizations have contributed. “

“The Lions club in particular has already started with their silversword gardens on Mauna Loa.” (Nina (Mrs Leo) Lycurgus, Star-bulletin, March 24, 1951)

By 1954, the Territory had spent about $100,000 for the road above 10,000 feet and had not gotten very close to either the “Gardens of the World,” a “snow road,” or a drive in volcano, not to mention the employment opportunities that had been expected. (Ellis)

On June 28, 1956, a larger building at 11,150 feet was dedicated as the Mauna Loa Slope Observatory, which in time became known as the Mauna Loa Observatory.

Mr. Vance was administrator of the Hilo Hospital from 1960 through 1965. He and the Hilo Lions Club were active in supporting the observatory from their strong political base during this period. (Ellis)

They, ultimately, did rough grade a road from Kulani to the top of Mauna Loa; however, “the three-hour ride up the road was enough to shake out what little enthusiasm they might have had.”

A four-mile link to the Saddle Road was made and opened on April 27, 1963. Thereafter, this was the route used to get to the observatory, with the road through Kulani not being used for this purpose anymore.

Bombing the River of Fire

Like most Hawaiian eruptions, the eruptive activity was immediately preceded by a swarm of earthquakes, followed by tremor. Mauna Loa (“Long Mountain”) began erupting at 6:20 pm on November 21, 1935.

The eruption started with a curtain of fountains near North Pit within the summit caldera, Mokuʻāweoweo. The vents migrated 2-miles down the northeast rift zone.

During the six days of the main event, fissures opened up along the northeast rift zone of the mountain, fountaining lava 200- to 300-feet into the air.

On November 26, the summit eruption died and the northeast rift activity was reduced to a single vent at the 11,400-foot elevation. A small vent also opened up further below on the north flank of the mountain at the 8,600-foot elevation. (USGS)

Lava flows from Mauna Loa were generally fast-moving and voluminous. Lava moved relentlessly at a rate of five-miles each day; it pooled up between Mauna Kea and Mauna Loa at about where the Saddle Road is situated.

The ponded lava eventually began to follow the lay of the land, a natural drainage … Then, things “got interesting.” Lava was heading directly toward Hilo. (USGS)

Dr. Thomas A Jaggar Jr, the government volcanologist, estimated that the flow would reach Hilo by January 9, 1936. He suggested using dynamite to collapse lava tubes near the source of the flow in order to stop or divert it.

Explosives were first suggested as a means to divert lava flows threatening Hilo during the eruption of 1881. However, Jaggar’s plan of mule teams hiking the explosives up the mountain would take far too long – the lava flows were moving a mile a day.

Guido Giacometti, a friend of Jaggar, had suggested using US Army Air Corps bombers to precisely deliver explosives. Jaggar agreed, and the call was made.

The US Army Air Corps approved, and the mission and plans to strategically bomb Mauna Loa were set into motion. Lieutenant Colonel George Smith Patton was called on to oversee the Army operation. (He’s the same Patton who would go on to WWII fame.)

Lava tubes are cooled and hardened outer crusts of lava which provide insulation for the faster-flowing, molten rock inside. Such a conduit enables lava to move faster and farther.

The theory was bombs would destroy the lava tubes, robbing lava of an easy transport channel and exposing more of the lava to the air, slowing and cooling it further. (BBC)

On December 26, 1935, six Keystone B-3A bombers of the 23d Bomb Squadron and four Keystone LB-6A light bombers from the 72d Bomb Squadron joined the rendezvous circle in the predawn darkness off Diamond Head, and then headed to Hilo.

Jaggar briefed the crews on the methods he had in mind to divert the lava flow. He then flew over the volcano to assess the flows and select the right points for bombing.

8:30 am, December 27, 1935, the first five bombers departed on the bombing mission. (A second flight of five aircraft was planned for the afternoon.) Each plane carried two 300-pound practice bombs (for practice and sighting,) as well as two 600-pound Mk I demolition bombs (355 pounds of TNT each.)

The bombers opened formation and fell into a huge circle for a follow-the-leader dummy run over the target area. They were flying at about 12,500-feet, not far above the 8,600-foot altitude of the volcano’s flows.

As the lead pilot tipped the control column forward for his run he lowered the wheels, so that by the time he neared the clump of koa trees which served as reference point his plane would be moving only a little faster than the 65-mph landing speed.

‘OK?’ he called to his bombardier as they began their climb after passing over the flow. Standard radio-voice procedure was unneeded. … ‘OK,’ the bombardier grunted. (Johnson)

Five of the twenty bombs struck molten lava directly, most of the others impacted solidified lava along the flow channel margins; one of them turned out a dud.

“Colonel William C Capp, a pilot who bombed the lower target, reported direct hits on the channel, observing a sheet of red, molten rock that was thrown up to about 200′ elevation and that flying debris made small holes in his lower wing.”

“Bombs that impacted on solidified, vesicular pāhoehoe along the flow margin produced craters averaging 6.7-m diameters and 2.0-m depth….” (Swopes)

“Pilots observed that several bombs collapsed thin lava tube roofs, although in no case was sufficient roof material imploded into the tube to cause blockage.”

Jagger wrote that “the violent release of lava, of gas and of hydrostatic pressures at the source robbed the lower flow of its substance, and of its heat.”

The lava stopped flowing on January 2, 1936. The effectiveness of the lava bombing is disputed by some volcanologist. (USGS)

‘Āinapō Trail

The canoe was a principal means of travel in ancient Hawai‘i; land travel was only foot traffic, over little more than trails and pathways.

Extensive cross-country trail networks enabled gathering of food and water and harvesting of materials for shelter, clothing, medicine, religious observances and other necessities for survival.

Ancient trails, those developed before western contact in 1778, facilitated trading between upland and coastal villages and communications between ahupua‘a and extended families.

These trails were usually narrow, following the topography of the land. Sometimes, over ‘a‘ā lava, they were paved with water-worn stones.

One such overland trail, leading to Mokuʻāweoweo, the summit crater at the summit of Mauna Loa, is ‘Āinapō Trail (darkened land (often heavy with fog)).

It is a narrow, single-file, twisting, and occasionally slightly abraded trail above the 11,600 elevation. It leads up the broad southeast flank of Mauna Loa volcano to and along the east side of Mokuʻāweoweo, the major summit crater (HHF)

Hawaiians laid out the ‘Āinapō foot trail to assure availability of shelter, drinking water, and firewood between their nearest permanent settlement, Kapāpala village, and Mokuʻāweoweo. Kapāpala village could be reached over easy-grade trails from the coastal Hawaiian settlements.

Most Mauna Loa ascents by Hawaiians were made during summit eruptions, when the volcano goddess Pele was present, to honor her with chanted prayers and offerings; and perhaps at other times to honor a site she frequented. (NPS)

“The Hawaiian style of ascent to Mokuʻāweoweo lay in moving upslope in easy stages to lessen fatigue and permit acclimatization to the increasingly rarefied atmosphere.

The major stages were a series of overnight camps, each complete with small, warm, thatched houses and well supplied with food, drinking liquid, and firewood. In each camp, the elite were supported in the style of Hawaiian high chiefs. The lesser stages consisted of frequent rest stops, perhaps in natural rock shelters, warmed by fires as necessary. (NPS)

In 1840, Lt Charles Wilkes, as part of the US Exploring Expedition, came to Hawai‘i to conduct experiments and make observations, including swinging pendulums on Mauna Loa’s summit to calculate the force of gravity. They hiked from Hilo to the summit.

Wilkes substituted his own route for the Hawaiian ‘Āinapō trail. Wilkes’ line of march was through wooded country, but without streams or waterholes. Shoes of the Caucasians scuffed and soles abraded on the lava they crossed.

Most of the Hawaiians were barefoot. To mark the path for the straggling porters, Wilkes’ associates built fires and blazed trees. Bushes were broken with their tops laid down to indicate the direction of travel. (NPS)

Much unnecessary thirst, hunger, cold, altitude sickness, fatigue, and snowblindness were suffered by both Caucasians and Hawaiians of the expedition when Wilkes substituted his own route for the Hawaiian ‘Āinapō trail.

‘Mountain’ sickness, probably caused from the combination of fatigue, dehydration, chill, hunger, and the altitude, was prevalent.

To the rescue came the Hawaiian guides ‘Ragsdale’ and Keaweehu, a famous bird catcher. Both had apparently been waiting at Kapāpala for the expedition to arrive and planned to guide the expedition up the ‘Āinapō trail.

Ragsdale was hired to supply water for the camp. His men delivered it the next day – fifteen gallons carried in open-top vessels over the trackless ten miles of rugged lavas which separated Wilkes’ camp from the ‘Āinapō trail.

At about the same elevation on the Āinapō was a large lava tube with pools of water inside. This tube was used by Hawaiians on the ‘Āinapō trail and was easily supplied with grass (for insulation from the cold ground) and firewood from a point on the trail not far below. (NPS)

Up until around 1916, the customary route to the summit of Mauna Loa was the 34-mile long ‘Āinapō Trail. Most Mauna Loa ascents by Hawaiians were made during summit eruptions, when the volcano goddess Pele was present, to honor her with chanted prayers and offerings. (HHF)

In 1916, With the assistance of the US Army, Thomas A Jaggar, a geologist from the Massachusetts Institute of Technology (MIT) had a trail constructed from Kīlauea to the Mauna Loa summit along the northeast flank of the mountain.

That year, the summit of Mauna Loa, the Army-built trail, and the summit of Kilauea volcano were incorporated within Hawaii National Park, established by Congress.

With the trail completed, horses and mules could go as far as Pu‘u ‘Ula‘ula (Red Hill), where a 10-man cabin and 12-horse stable had been built. The remaining 10-mile trail to the summit was pedestrian only.

After 1916, for the next half century, there were two trails to the summit, but the Āinapō received diminishing usage and was not maintained. Below the barren lavas, the savannah-forest areas through which the ‘Āinapō passed became ranching country private land through which public passage was discouraged. (NPS)

From the trailhead, ʻĀinapō Trail ascends 7,600-feet in 10.2 miles to the National Park Service cabin on the rim of Mokuʻāweoweo crater.

Vegetation varies from mixed mesic koa /ʻōhiʻa forest to alpine stone desert. Intermittent, and in places infrequent, stacks of loose lava boulders (ahu) line the sides of the trail.

Abraded spots occur only on the rare surface types subject to pockmarking by metal blows; this was done by iron-shod hooves since 1870s, when horses and mules began to be used. (NPS)

Day use of ʻĀinapō trail does not require a permit; however, hikers are required to contact Kapāpala Ranch at 808-928-8403 to obtain the combination for the locked gate.

Everyone using this public access will sign in and out on the log sheet located in the mailbox on the gate.

Reservations and permits for camping at the trail shelter may be obtained from Hawaiʻi District Division of Forestry and Wildlife, at 808-974-4221 or at the link below. Hikers continuing to the summit need to register with the National Park Rangers (808 985-6000). (DLNR)
