“When this earth was created, Nature, it seems, was more concerned with things other than road making, as witness the (attached) illustration.”

“The pictures shown herewith were taken during one of Professor T. A. Jaggar’s daily trips along one of the stretches which Nature forgot to pave with crushed stone and asphalt.”

“Professor Jaggar, of the Massachusetts Institute of Technology, is a noted volcano specialist, and most of his work is done around the craters of the smouldering mountains he studies.”

“As director of the Hawaii Volcano Observatory, he has devoted nearly all of his attention to the famous Mauna Loa and Kilauea craters, living right at the scene of his activities and experiments for the past twelve years.”

“Although hazardous, Professor Jaggar makes it his business to get as close as possible to the scenes of eruption and volcanic action in order to obtain first-hand photographs, lava samples, temperature readings, and other valuable scientific data.”

“In this field of work one needs a ‘business car’ just as much as in any other calling, and so the scientist got himself a car that would be not only easy of operation but would stand the terrible strain of volcano climbing as well.”

“The professor bought a Ford and made a few alterations to suit his particular needs, with the result that the machine became more efficient than beautiful.”

“If you will refer to the picture, you will note that the fenders and doors are stripped, and that dual wheels are installed on the rear axle, which enable the car to travel over boulders 10 and 12 inches high with little difficulty, and also to go through deep sand and “aa,” which is the Hawaiian for clinker lava.”

“After having seen about half a dozen years of the most strenuous service imaginable, the car is still ‘going strong.’”

“Mauna Loa is the largest, although not the highest, volcano in the world, being 13,760 feet above sea level ; Kilauea crater is an immense cavity three miles long by two miles wide on the east slope of Mauna Loa.”

“These immense caldrons are reached by means of a very steep, rough trail, which more than proves the marvelous durability of the only car that has ascended it.”

“At the present time nothing but a pack trail leads to the summit of Mauna Loa, and so the Ford cannot be driven to the top, but it has plenty to do in the vicinity of Kilauea and also on the vast flanks of Mauna Loa, where various eruptions have taken place.”

“About a mile distant from Kilauea is a smaller, extinct crater known as ‘Little Kilauea.’ While it is no longer a sea of molten lava, like its near-by active brothers, nevertheless its surface is hot enough in places to be detrimental to the rubber tires on Professor Jaggar’s Ford, and uncomfortable for the feet of his dog.”

“The machine is often ‘cruised’ over freshly flowed lava that is not yet cool in order to make scientific investigations.”

“Professor Jaggar has set up a drilling rig here for the purpose of getting down into the hot lava bed directly beneath the surface to determine the subterranean temperatures and to take samples of gases.”

“The Ford car has been of indispensable assistance in transporting the equipment to and across the terribly rough crater floor; also in carrying the large quantity of water needed when drilling into the hot lava.”

“Heavy photographic equipment is easily taken care of by the car, and specimens are often gathered which have to be taken back to the observatory for study.”

“Because of these and numerous other services rendered by the car, no limit can be placed upon its value to the expedition.”

“At times, the lava in the crater rises rapidly and overflows, spreading destruction on its path. Occurrences like this have been the occasion for several intensive and hazardous expeditions by Professor Jaggar and his party.”

“Professor Jaggar has discovered many facts of scientific importance, and is working on plans for utilizing the heat of the volcano for commercial purposes. He believes that ways can be found to generate a large amount of electricity.”

“First, he hopes that a near-by hotel can be supplied with all the current needed; and eventually, if practical ways are found for harnessing the energy, the entire island will get its power from the volcano.” (This entire post is from Ford News, July 22, 1923.)

Whitney Laboratory of Seismology

When a hotel on the rim of Kilauea caldera became a permanent facility in 1866, its series of guest registers became a repository of reports and observations by the guests, an almost daily record (by observers who varied from the scientist to the joker) of earthquakes felt and unfelt and of volcanism seen and unseen on Kilauea and Mauna Loa.

In the hope that science could close the gaps in geological knowledge and learn to predict earthquakes and eruptions, some New Englanders were willing for humanitarian reasons to finance foreign trips and support work abroad for scientists.

For instance, the Springfield (Massachusetts) Volcanic Research Society supported, at least in part, the travels and studies of Frank A. Perret, an electrical engineer and inventor turned volcanologist who became well known for his studies at Vesuvius, Etna, and Stromboli. The Springfield society also helped support Perret’s 1911 work at Kilauea.

It was in this climate of opinion that the trustees of the estates of Edward and Caroline Whitney gave to the Massachusetts Institute of Technology (MIT) the sum of $25,000 for a memorial fund; the principal and interest were to be expended at MIT’s discretion for research or teaching in geophysics, especially seismology.

Investigations in Hawaii were recommended. The Whitney fund was deeded to MIT by the trustees on July 1, 1909, and three years later a group of twelve other New Englanders supplied MIT with supplemental funds for geophysical research in Hawaii.

MIT gave Thomas A Jaggar a leave of absence in December 1911 and directed him to Kilauea to continue the investigations made in the summer of 1909. Jaggar arrived at Kilauea on January 17, 1912.

Work then started on what would be the Hawaiian Volcano Observatory (Observatory.) A cellar excavation on the north rim of Kilauea caldera started on February 16, 1912, marking the beginning of permanent facilities for the Observatory.

The Observatory was largely the creation of Jaggar (1871-1953), then a MIT professor, who recognized the advantages, for the study of volcanism, of onsite facilities at an active volcano.

Wooden stakes marked the corners of a rectangle about 24-feet long by 22-feet wide only about 20-feet from the cliff-like rim of Kilauea caldera on the Island of Hawaii.

A hole was to be dug by hand. The diggers were prisoners of the Territory of Hawaii, sentenced to a term of hard labor. The prisoners dug through almost six feet of volcanic ash and pumice to a layer of thick pahoehoe lava – a firm base for the concrete piers on which seismometers would be anchored.

Jaggar had contracted with Hackfeld for the forms and concrete work for the seismometer vault, and for the wooden structures that were to stand over and adjacent to the vault – the rim-side facilities of the Hawaiian Volcano Observatory.

The result was “a basement room, eighteen feet square, with piers and floor of concrete, reposing upon the upper surface of the basalt, and high walls of concrete (and became known as) the Whitney Laboratory of Seismology.” A building was built above.

“A constant emanation of hot steam from cracks in contact with the concrete walls keeps this room at a fairly uniform temperature and thus improves it for the purposes of seismology.” (Apple)

“Concrete tables on the floor of the cellar held the pair of east-west and north-south horizontal pendulums, recording with delicate pens on smoked paper, stretched over a chronograph drum.”

“These paper records, removed every day and fixed with shellac varnish, became the seismograms of the permanent files. Long belts of wavy lines on each paper exhibited seconds, minutes, and hours; and when a sharp zigzag in one of the lines occurred, it was evidence of either a local or a distant earthquake.” (Jaggar)

However, the “oppressive warmth caused by the natural steam heat” added challenges to the scientists’ daily lives. Scientists through the active life of the vault bundled up in wooly sweaters, scarfs, and raincoats to walk to the vault through the chilling rains and fog at 4,000-foot altitude and then peeled clown to undershirts when they entered the vault to attend the instruments.

Being a basement vault with a building above also created problems. Even in calm weather, movements of the building were recorded by the seismometers in the vault below.

Winter Kona storms swept high winds from the south across Kilauea caldera, hitting with full force against the north rim and causing such rocking and trembling of the building above as to mask the records on the seismograms.

In the winter of 1915-16, gale-force winds stripped the sheets of corrugated iron from the roof of the building. Rain water in the offices above poured into the vault to wash away the seismograms on their drums, flood the floor, and soak the instruments. Repairs took weeks.

On December 19, 1921, the nearby Volcano House began to run a generator for the first electric lights at Kilauea. Variations in the engine speed as well as the exact times of starting and stopping were duly recorded by seismometers in the Whitney vault.

On February 11, 1940, the main Volcano House burned to the ground, and this led to the relocating of the Observatory facilities. (The present Volcano House was opened for business in November 1941.)

That year, the building above the observatory was dismantled, and a reinforced-concrete slab was poured by the Civilian Conservation Corps (CCC) to become the vault’s new roof. The slab was covered with 18-inches of topsoil (the vault mound is on the crater side of the Volcano House.)

On December 28, 1947, the Hawaiian Volcano Observatory was transferred within the Department of the Interior from the National Park Service to the United States Geological Survey.

In 1948, the Observatory was moved to a building at the top of Uwekahuna Bluff on the northwest rim of Kilauea caldera; a new and larger building there was completed in 1986. (The bulk of the information here comes from Russell Apple’s (retired National Park Service historian) history of the Hawaiian Volcano Observatory.)

DUKW (Duck)

“Auto that sails the seas and boat that runs on land”

“An Alaskan expedition to study explosive Mount Katwain in 1927 furnished Dr (Thomas Augustus) Jaggar with the motive for developing an amphibious motor car.”

“After several months of experimentation, he completed his pioneer water bug and dubbed it ‘Ohiki,’ which is Hawaiian for sand crab.” (Popular Mechanics)

“In preparation for this expedition, the Hawaii Volcanoes Observatory machine shop built a wooden amphibious boat around a ‘low-geared small motor car with balloon tires,’ that Jaggar had used over tundra and beach of the Alaskan Peninsula in 1927.”

“Inlets, rivers, and rocks were obstacles that made Jaggar mentally design modifications of the car into a ‘car-skiff.’”

Jaggar invented the first practical wheeled amphibian. (Popular Mechanics)

“She first took to the sea at Ninoʻole Cove in the Kaʻū District, and she quickly revealed the need for additional work.” (USGS)

“Several hundred skeptical spectators witnessed the formal launching January 17, 1928, at Hilo, Hawaiʻi. Many wagers were lost as the Ohiki lumbered off the highway and trundled along the beach into the water.”

After modifications (freeboard raised, length slightly increased, paddle-wheels enlarged, a winch and cable mounted in bow, 5-horsepower outboard motor added,) an extended trip was made along the west coast of the Island of Hawaii to make beach and sea tests.

Lorrin Thurston went along as a passenger and publicity man; Mrs Jaggar served as stewardess. The car with the boat body excited all the roadside children of Kona with delight. (USGS)

“Dr. Jaggar’s initial amphibian was a skiff 21-feet long with a beam of five feet four inches, mounted on an elongated Ford chassis … just forward and mounted through the sides of the boat was a Ruckstall axle to which sidewheel paddles were attached … the front wheels were disked and served as rudders.” (Popular Mechanics)

“Jaggar’s Ohiki made a speed of about 4 mi/h in water with the combined power of paddle wheels and outboard motor… It made more than 20 mi/h over highways.” (USGS)

He later created another amphibian, the Honukai (sea turtle;) it was a twin-screw steel amphibian, built in Chicago by the Powell Mobile-Boat Corp.

In 1928, when the National Geographic Society joined with the USGS to sponsor an expedition with Jaggar in charge to map, photograph, and survey in the Aleutians around Pavlof Volcano, the Society supplied an amphibious boat.

In the 400-miles along the coast of Alaska, from Shumagin Islands to King Cove, the expedition did not even have to pump up the tires. (USGS)

The Honukai’s numerous excessively low gears even enabled them to drive up to the snowline and bring out the heavy fur and bones of a bear that Jaggar had shot on the snowy volcano, Mount Dana. Jaggar brought the Honukai back to Hawaii with him and based it in Kona. (Popular Mechanics)

“As a result of his experiences and design work with the Ohiki and the Honukai, Jaggar was later able to help the US Army with the design of amphibious vehicles for World War II, and he received in 1945 the Franklin L Burr Prize of the National Geographic Society for this work.” (USGS)

In 1942, the Army, faced with challenges in landing troops and supplies, modified a 1 ½ ton GMC truck – it was called the DUKW (D = built in 1942; U = amphibious 2½ ton truck; K = front wheel drive and W = rear wheel drive.) (Army Transportation Museum)

Today, we simply call these vehicles ‘Ducks.’

Jaggar was considered grandfather of the ‘Duck,’ which has played a prominent part in amphibious landings both in the European and South Pacific theaters of war. (Mount Caramel, February 27, 1945)

(Lorrin Thurston and George Lycurgus were instrumental in getting the volcano recognized as Hawaiʻi Volcanoes National Park. In 1912, Jaggar moved to Kilauea to start the observatory, studying volcanoes.)

(On August 1, 1916, President Woodrow Wilson signed the country’s 13th National Park into existence – Hawaiʻi National Park (later (1961) split into Haleakalā National Park and Hawaiʻi Volcanoes National Park.)

Thomas Augustus Jaggar, Jr

“To helpmeet and campmate, Isabel Jaggar,
Whose horse crushed her against a tree …
Whose gloves fell into a red hot crack and burned up …
Who slept in a lava tunnel …
Beside the immortal remains of a desiccated billy goat …
And loved it all.”
(Thomas Jaggar dedication of book in 1945, USGS)

“In 1906, already a much-published, respected, well-known geologist, writer and lecturer, he became head of MIT’s department of geology. Jaggar saw the need for full-time, on-site study of volcanoes.”

“He had long deplored that to date, especially in America, it was only after news of an eruption was received that geologists rushed from academic centers to study volcanism.”

“There was generally no trained observer there beforehand, and scientists from afar often arrived after the eruption was over. There was then only one volcano observatory in the world, that at Vesuvius established in 1847.” (USGS)

In February 1912, prisoners, sentenced to a term of hard labor, started digging a cellar on the north rim of Kilauea Crater. The prisoners dug through almost 6-feet of volcanic ash and pumice to a layer of thick pāhoehoe lava, a firm base for the concrete piers on which seismometers would be anchored.

This was the result of “a visit to the Volcano of Kilauea on October 7th, 1909 … by the very distinguished English vulcanologist Dr. Tempest Anderson of York, and the well-known professors in the Massachusetts Institute of Technology, TA Jaggar, Jr, and RA Daly, the last two interested in the establishment of a permanent observatory at Kilauea”. (Brigham)

Jaggar had traveled to the Islands at his own expense. He left MIT, moved to Kilauea to start the observatory, and devoted the remainder of his life to a study of volcanoes. He also had a home in Keopuka, South Kona.

Jaggar was born in Philadelphia, Pennsylvania in 1871, the son of an Episcopal Bishop. A childhood fascination with the natural world eventually translated into three geology degrees from Harvard (AB, AM and PhD (1897.)) He studied in Munich and Heidelberg, and then began teaching at Harvard, later at MIT.

His years as a graduate student and young professor were spent in the laboratory. He felt strongly that experimentation was the key to understanding earth science. Jaggar constructed water flumes bedded by sand and gravel in order to understand stream erosion and melted rocks in furnaces to study the behavior of magmas. (USGS)

Jaggar witnessed the deadly aftermath of volcanic and seismic activity during a decade-long exploration of volcanoes around the world.

The devastation he observed, particularly that caused by the 1902 eruption of Mount Pelée on the Caribbean Island of Martinique, led Jaggar to his vision and life-long work to “protect life and property on the basis of sound scientific achievement” by establishing Earth observatories throughout the world. (USGS)

When he 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)

About this time, about 800 Buffalo Soldiers from the 25th Regiment had been assigned to garrison duty at Schofield Barracks. Given their experience in Parks on the continent, some of the soldiers were called upon to assist at the volcanoes on the Island of Hawaiʻi.

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)

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.

Although Jaggar had married Helen Kline in 1903 and the couple had two children, Helen did not accompany Jaggar to accept his post as director of the Hawaiian Volcano Observatory in 1911, and a divorce followed (filed in 1914.)

In 1917, Jaggar married a coworker at the volcano observatory, Isabel P. Maydwell; she was his wife, assistant and companion for the rest of his life. (USGS)

On August 1, 1916, President Woodrow Wilson signed the country’s 13th National Park into existence – Hawaiʻi National Park. At first, the park consisted of only the summits of Kīlauea and Mauna Loa on Hawaiʻi and Haleakalā on Maui.

Eventually, Kilauea Caldera was added to the park, followed by the forests of Mauna Loa, the Kaʻū Desert, the rain forest of Olaʻa and the Kalapana archaeological area of the Puna/Kaʻū Historic District.

The National Park Service, within the federal Department of Interior, was created on August 25, 1916 by Congress through the National Park Service Organic Act.

In 1916, Thurston, recognizing the long tradition of soldiers and sailors who had visited the area, proposed the establishment of a military camp at Kīlauea. Thurston promoted his idea and was able to raise enough funds through public subscription for the construction of buildings and other improvements. By the fall of 1916, the first group of soldiers arrived at Kīlauea Military Camp (KMC.) (NPS)

Later, in the 1930s, the Civilian Conservation Corps (CCC) built research offices, hiking trails and laid the foundations for much of the infrastructure and roads within the Hawaiʻi Volcanoes and other parks across the country.

On, July 1, 1961, Hawaiʻi National Park’s units were separated and re-designated as Haleakalā National Park and Hawaiʻi Volcanoes National Park.

Throughout his career, Jaggar pursued his goal of mitigating the negative impacts of natural hazards on humans through the continuous study of volcanoes and earthquakes, both in Hawaiʻi and around the world.

He retired in 1940 and moved to Honolulu. After leaving, Jaggar continued his research at the University of Hawai‘i at Mānoa until his death on January 17, 1953, 41-years after beginning his work on Kilauea. (USGS)
