Haleakalā Trail and Highway

On the morning of November 26, 1778, Captain James Cook awoke to the sight of the northern coast of Maui. “Next morning there lay the land, the island of Maui, with its ‘elevated saddle hill’ – the extinct 10,000 foot volcano Haleakala …”

“… rising to its summit above the clouds, and descending gently towards the deep ravines and falling waters of that steep rocky coast, where the trade wind hurled other waters into perpetual surf.” This was the first documented sighting of the island. (Fredericksen)

“[T]he chief pride of Maui is her dead volcano of Haleakala”. (Mark Twain, Roughing It, 1866) “The object which usually attracts strangers to Maui is the great dead volcano of Haleakala, ‘The house of the sun’. (Isabella Bird, 1873)

“This mountain … is the largest extinct volcano in the world, its terminal crater being nineteen miles in circumference at a height of more than ten thousand feet. It, and its spurs, slopes, and clusters of small craters form East Maui.” (Isabella Bird, 1873)

Haleakalā was thought to have been known to the ancient Hawaiians by any one of five names: “Haleakalā,” “Haleokalā,” “Heleakalā,” “Aheleakalā” and “Halekalā.” (Hawaiʻi National Park Superintendent Monthly Report, December 1939)

“According of Abraham Fornander, the name Haleakala is a “misnomer”. He explains the ancient name of is Ahelekala. “The ancient name of Maui’s famous crater which means ‘rays of the sun’ …”

“… and it was these which the demigod Maui snared and broke off to retard the sun in its daily course so that his mother might be able to dry her kapas.” … He goes on to say that the word `alehe is a variant form of `ahele—both of which literally mean “to snare”. (Fredericksen)

The first visit to Haleakalā by non-Hawaiians occurred in August 1828 when missionaries Lorrin Andrews and Jonathan Green, along with Dr. Gerrit P. Judd, physician, visited the crater.

They were followed by a US Navy expedition led by Commander Charles Wilkes in 1841, and later, others. Significant public interest was generated by written accounts of these visits that determined that Haleakalā would eventually become a destination for tourism.  (NPS, CCC Oral Histories)

Until 1935, the primary means of getting to Haleakalā was walking or on horseback, and this continued to be the case for the first three decades of the twentieth century. As late as 1932, the Inter-Island Steamship Company and the Maui Chamber arranged trips on horseback to Haleakalā Crater.  (NPS, CCC Oral Histories)

Thomas Vint (NPS Chief Landscape Architect) described the trip by horseback that he made in 1930: “The trip is now made from the town of Wailuk[u] which contains the principle [sic] hotel on the island of Maui that caters to tourist travel …The combined auto and horse back trip to the 10,000-foot summit may be made from noon to noon from Wailuku, spending the night at the top.”

“Trips into the crater are made from the rim rest house as a base.”  Vint concluded that “another rest house at the far end of the crater is needed. To see the crater properly, one should camp overnight, making a two-day trip from the present rest house.” (NPS, CCC Oral Histories)

“Without a paved road to the summit, however, Haleakalā remained distant and inaccessible for the vast majority of the Maui public, except for adjacent property owners, tourists of means, and hunters who lived in the upcountry or Kula region of the island.”

“The need for a road to Haleakalā had been the subject of interest by the local press as well as Maui politicians since 1912, when the Hawaiian Promotion Committee had to use ‘fourteen pack and saddle animals’ to reach the summit from Olinda.” (NPS, CCC Oral Histories)

AH Ford of Mid-Pacific Magazine was quoted in the local press as stating: “In a little while [the] Haleakalā trips are going to adjust themselves to the purses of the tourist and there will be sufficient traffic to encourage regular excursions to Haleakalā [and] through the crater…a wonder trip, unsurpassed by any three or four [hour] outing to be had in any other portion of the globe.” (Maui News, August 9, 1913)

“After a failed attempt by motorcar in 1917, the first vehicle, a tractor driven by Joaquin Souza, finally reached the summit of Haleakalā on July 4, 1931.  The stunt, which took two hours and thirty minutes to complete, was part of the local U.S. Independence Day festivities”.

It “was reported by the newspaper beneath the headline, “First Vehicle [to] Ever Reach Top” (Maui News, July 8, 1931).  (NPS, CCC Oral Histories)

Haleakalā Road (now known as Haleakalā Highway) was finally completed in 1935; it opened with great fanfare. “All Maui was up in the air today, 10,032 feet up! … Whole Mainland Hears Road Opening by Radio … The story came over radio station KGU … The ceremony was caught up in Honolulu and taken to San Francisco, then distributed over the vast NBC hook-up.” (Maui News Feb 24, 1935)”

“On November 30, 1929, work began. On February 21, 1935, the last surfacing was laid.” “An official checker clocked 304 automobiles into the world’s highest parking spaces and those autos are estimated to have carried 1500 excursionists and local residents to the two-hour program.”  (Maui News Feb 24, 1935)

The number of visitors to Haleakalā increased substantially, reaching 16,300 within a year. In 1938, the numbers decreased slightly to 14,156 because of a maritime and shipping strike, but continued to rise in the following years until reaching 29,935 in 1940.  (NPS) (National Park Records show approximately 853,700 recreation visits in 2025,)

The increase in visitors was “greatly in excess of expectations…compared with the few hundreds who visited the crater before construction of the Haleakalā [R]oad. (Hawaii National Park Superintendent Annual Report 1935, NPS)

The Civilian Conservation Corps (CCC) began in 1937, succeeding the Emergency Conservation Work agency (which started in 1933). In 1939, the CCC became part of the Federal Security Agency. It was eliminated in 1943. (UH Mānoa)

From April 1934 until May 13, 1941, the CCC operated a “side camp” in the Haleakalā Section of the Hawaiʻi National Park; CCC participants were housed in tents and moved to where the work areas were.  (NPS)

Major park improvements through the CCC program on Haleakalā included the construction of the approximately 11-mile Haleakalā Road, Haleakalā Observation Station, two Comfort Stations (public toilets) and the Checking Station and Office at the park entrance.  Several trail projects were completed within the Park.  (NPS)

Waikamoi

The kahakai (shoreline) and the lowlands were the Wao Kanaka (the realm of people,) where fishing, farming, and activities of daily life took place. Further inland was the Wao Kele (the inland forest region) and above this was the Wao Akua (the realm of the gods.)

In ancient Hawaii, the Wao Akua was accessed only by trained professionals for specific purposes (medicinal practitioners gathered specific plants and bird men caught birds for their vibrant feathers,) after respects were paid and permission was granted.

Even then, however, entry into the Wao Akua (a dense native cloud forest) was seldom. It was recognized that the health of the watershed in the Wao Akua was essential to the health of the Wao Kanaka. (Hana Pono)

Hawaiians did not as a matter of course penetrate the Wao Akua if the trees they needed could be gotten elsewhere, because of the priority of promoting new growth through non-disturbance of seed-producing forest areas.

Hawaiians realized the importance of the food source and the regenerative energy of the forest. Therefore it was necessary to leave some areas or groves of trees as they stood originally, thus the name Wao Akua. (DLNR)

Waikamoi takes its name from a variety of taro named for a variety of fish, the moi. The moi kalo (taro) is a very nice tasty variety good for wetland, flood style irrigation taken to great heights by the Hawaiians system of aqueducts and loʻi kalo.

The naming of Waikamoi indicates that at the lower elevations, the stream fed loʻi kalo, taro patches, of moi taro which was a favorite of the people living in the area. (Hana Pono)

Roaming ungulates (typically cattle and pigs) and non-native habitat-modifying weeds/plants, insects and other invasive species took their toll on the mauka forested resources.

In 1876, the Hawaiian legislature also passed ‘An Act for the Protection and Preservation of Woods and Forests; this was the first step in creating what would later become the forest reserve program.

Then, on April 25, 1903, the legislature created Hawaiʻi’s forest reserve, sparking the largest public-private conservation partnership in the history of the state. Ralph S. Hosmer was Hawaiʻi’s first Superintendent of Forestry. (Hosmer’s Grove in Haleakala National Park adjoins the Waikamoi Preserve.)

In 1983, Waikamoi Preserve on the slopes of Haleakala on Maui became a reality when the Haleakala Ranch granted a conservation easement to The Nature Conservancy (TNC) over 5,230-acres (in 2014, Alexander & Baldwin conveyed a conservation easement over an additional 3,721-adjacent acres, bringing the total to 8,951-acres – the largest private nature preserve in the Islands.)

The preserve protects part of the 100,000-acre East Maui Watershed, which provides 60-billion gallons of clean water annually to Maui’s residents, businesses and agricultural community.

It is a sanctuary for native Hawaiian species, many of them endangered or rare (including several native birds: the rare ‘akohekohe, the scarlet ‘i‘iwi, the crimson ‘apapane, the bright green ‘amakihi, the yellow-green Maui creeper, the pueo (Hawaiian owl,) nene (Hawaiian goose) and the native ‘ua‘u (dark-rumped petrel.))

The preserve also shelters a large variety of native ferns, herbs, shrubs and trees that reflect the biodiversity of Maui; many are rare plants unique to East Maui.

The Nature Conservancy protects the native species that live in Waikamoi by managing this koa and ʻohi‘a forest against threats to this diverse forest ecosystem. Like other Hawai‘i rain forests, invasive species and feral predators threaten Waikamoi’s delicate ecosystem.

Waikamoi Preserve is managed in partnership with the State Department of Land & Natural Resources through the Natural Area Partnership Program. (TNC)

The National Park Service leads hikes through Waikamoi on Mondays and Thursdays; the hike focuses on the unique history, plants and animals of the area. Reservations are accepted up to one week in advance. Call (808) 572-4400. Please call early since there is limited space available.

While I was Director at DLNR, I was fortunate to have the opportunity to walk the boardwalk in the Waikamoi Preserve. The trail led to a deck in the middle of the forest … waaay cool.

Haleʻakala

Orphaned when young and with only an 8th grade education, Charles Reed Bishop arrived in the Islands on October 12, 1846 and became an astute financial businessman, and one of the wealthiest men in the kingdom from banking, agriculture, real estate and other investments.

In early 1847, Bishop met Bernice Pauahi Paki (she was still a student at the Chiefs’ Children’s School;) despite the opposition of Pauahi’s parents who wanted her to marry Lot Kapuaiwa (later, Kamehameha V,) Bishop courted and married Pauahi in 1850.

For the first few months of their marriage, Pauahi and Charles lived in homes of Judge Lorrin Andrews, first in his downtown residence, and later in a cottage in upper Nuʻuanu Valley, opposite the site of the present Maunaʻala (Royal Mausoleum.)

Like many Hawaiian homes of the time, this one had a name, Wananakoa, for the grove of koa trees in the yard. This was only temporary – they were building a home on property Bishop bought on the Diamond Head/Mauka corner of Hotel and Alakea Streets.

Meanwhile, Pauahi’s father, Paki, had completed the construction of his new residence on King Street (between Fort and Alakea.) (Bishop Street had not been built, yet, the property would be on the ʻEwa/Mauka corner of what is now Bishop and King Streets.)

This new home replaced Paki’s prior modest, thatched-roof home he called ʻAikupika (‘Egypt’) that had been on the same piece of property. (ʻAikupika is where Pauahi was born.)

The name Paki gave his new home has been translated by some as ‘House of the Sun’ or Haleakala, but he probably meant it to be Haleʻakala or the ‘Pink House,’ after the color of the stone used in its construction. (Kanahele)

By the standards of the day, Haleʻakala was a splendid structure that was probably the equal of any of the better homes and gardens in town.

It was a large two-story stone-and-frame building with lanai (porches), supported by pillars on both first and second floors, extending around at least three sides of the house. Its extensive gardens combined shrubbery, flowers and trees and included the special tamarind tree planted at Pauahi’s birth.

Clarice B Taylor stated that he really built the house “hoping Pauahi would marry Prince Lot and make her home with her parents.” It was bigger than he and his wife needed; Paki had sold his lands at Mākaha to raise the money for its construction. (Kanahele)

Paki and his wife Laura Konia raised Pauahi there. When Liliʻuokalani was born, she was hanai (adopted) to Paki and Konia. The two girls attended the Chief’s Children’s School (Royal School,) a boarding school, together, and were known for their studious demeanor.

The history of the home goes beyond the Paki family living quarters; some other interesting bits of Hawaiian history happened here.

Liliʻuokalani and John Dominis were married at Haleʻakala, “I was engaged to Mr Dominis for about two years and it was our intention to be married on the second day of September, 1862. … our wedding was delayed at the request of the king, Kamehameha IV, to the sixteenth of that month”.

“It was celebrated at the residence of Mr and Mrs Bishop, in the house which had been erected by my father, Paki, and which … is still one of the most beautiful and central of the mansions in Honolulu.”

“To it came all the high chiefs then living there, also the foreign residents; in fact, all the best society of the city. My husband took me at once to the estate known as Washington Place, which had been built by his father, and which is still my private residence.” (Queen Liliʻuokalani)

“There was a Baptism at the Residence of the Honorable CR Bishop, “Haleʻakala;” baptized was the child of the honorable (Princess Ruth) Keʻelikolani and JY Davis, and he was called, “Keolaokalani Paki Bihopa.”

The Honorable CR Bishop and Pauahi were those who bestowed the name, and Rev C Corwin is the one who performed the baptism.” (Hoku o ka Pakipika, February 2, 1863) (Keolaokalani was hanai to Pauahi; unfortunately, he died later that year.)

Duke Kahanamoku was born at Haleʻakala on August 24, 1890. (With respect to his name “Duke,” he was named after his father. The elder Kahanamoku was born during the Duke of Edinburgh’s visit to the islands in 1869 and was named after him.)

Haleʻakala was converted to Arlington Hotel.

On the afternoon of January 16, 1893, 162 sailors and Marines aboard the USS Boston in Honolulu Harbor came ashore. The property that Liliʻuokalani was raised in (Haleʻakala) served as ‘Camp Boston,’ the headquarters for the USS Boston’s landing force at the time of the overthrow of the Hawaiian monarchy, January 17, 1893.

In 1901, Honolulu had three high-class hotels, the Hawaiian Hotel (in downtown Honolulu, now the State Art Museum on Hotel Street,) the Arlington Hotel and the Moana Hotel (in Waikiki.)

“The Arlington Hotel has, for its principal building, a house once occupied by a Hawaiian princess, by whose estate it is now leased to the hotel proprietor (Thomas E Krouse.”) (Chipman, 1901) Krouse, unfortunately, committed suicide at the Arlington the next year.

“A Mrs Dudoit ran the place for a while as a boarding house, and she was followed by a Mr Hamilton Johnson. Both these houses were, however, on a small scale. Just seven and a half years ago it became known as the Arlington, six cottages were attached, the aviary and the cages of animals so familiar to us all were added.” (Pacific Commercial Advertiser, September 6, 1900)

“The place was maintained as a chief’s residence for many years. It can only have been turned to other uses during the past fifteen years at the outside. Mrs Bernice Pauahi Bishop left the estate to her husband, who turned the property over to the Kamehameha estates.” (Sereno Bishop; Pacific Commercial Advertiser, September 6, 1900)

“(Haleʻakala) has a most unique and interesting history. It is one of the most historic spots in all Honolulu, embracing as it does the scenes of joyousness under royalty, through the stirring days of ’93 … the pettinesses of a boarding house and down to the present day as the Arlington Hotel.” (Pacific Commercial Advertiser, September 6, 1900)

“The estate which had been so dear to us both in my childhood, the house built by my father, Paki, where I had lived as a girl, which was connected with many happy memories of my early life, from whence I had been married to Governor Dominis,”

“I could not help feeling ought to have been left to me. … This wish of my heart was not gratified, and at the present day strangers stroll through the grounds or lounge on the piazzas of that home once so dear to me.” (Liliʻuokalani)

Liliʻuokalani, Her Early Years

She was born September 2, 1838 and named Lydia Liliʻu Loloku Walania Wewehi Kamakaʻeha.   (The following is a summary of some of her early years – as told by her.)

At that time, children often were named in commemoration of an event.  Kuhina Nui Kīnaʻu had developed an eye infection at the time of Liliʻu’s birth.  She gave the child the names Liliʻu (smarting,) Loloku (tearful,) Walania (a burning pain) and Kamakaʻeha (sore eyes.)

“My father’s name was (Caesar Kaluaiku) Kapaʻakea, and my mother was (Analeʻa) Keohokālole; the latter was one of the fifteen counsellors of the king, Kamehameha III, who in 1840 gave the first written constitution to the Hawaiian people.”

“My great-grandfather, Keaweaheulu, the founder of the dynasty of the Kamehamehas, and Keōua, father of Kamehameha I, were own cousins (he was also brother of Mrs Bishop’s ancestress, Hākau,) and my great-grandaunt was the celebrated Queen Kapiʻolani, one of the first converts to Christianity.”

“As was then customary with the Hawaiian chiefs, my father was surrounded by hundreds of his own people, all of whom looked to him, and never in vain, for sustenance. He lived in a large grass house surrounded by smaller ones, which were the homes of those the most closely connected with his service.”

“But I was destined to grow up away from the house of my parents. Immediately after my birth I was wrapped in the finest soft tapa cloth, and taken to the house of another chief, by whom I was adopted.”

In her youth she was called “Lydia” or “Liliʻu.” (She was also known as Lydia Kamakaʻeha Pākī, with the chosen royal name of Liliʻuokalani, and her married name was Lydia K Dominis.)  As was the custom, she was hānai (adopted) to Abner Pākī and his wife Laura Kōnia (granddaughter of Kamehameha I.)

“…their only daughter, Bernice Pauahi (born December 19, 1831,) afterwards Mrs Charles R Bishop, was therefore my foster-sister. … I knew no other father or mother than my foster-parents, no other sister than Bernice.”    The two girls developed a close, loving relationship.

“(W)hen I met my own parents, it was with perhaps more of interest, yet always with the demeanor I would have shown to any strangers who noticed me.”

“My own father and mother had other children, ten in all, the most of them being adopted into other chiefs’ families; and although I knew that these were my own brothers and sisters, yet we met throughout my younger life as though we had not known our common parentage. This was, and indeed is, in accordance with Hawaiian customs.”

Liliʻu and Bernice lived on the property called Haleʻākala, in the house that Pākī built on King Street.  It was the ‘Pink House,’ made from coral (the house was named ʻAikupika (Egypt.))  (It is not clear where the ʻAikupika name came from.)

“At the age of four years I was sent to what was then known as the Royal School, because its pupils were exclusively persons whose claims to the throne were acknowledged. It was founded and conducted by Mr Amos S Cooke, who was assisted by his wife. It was a boarding-school, the pupils being allowed to return to their homes during vacation time, as well as for an occasional Sunday during the term.”

“Several of the pupils who were at school with me have subsequently become known in Hawaiian history.  There were four children of Kīnaʻu, daughter of Kamehameha I, the highest in rank of any of the women chiefs of her day; these were Moses, Lot (afterwards Kamehameha V,) Liholiho (afterwards Kamehameha IV) and Victoria”.

“Next came Lunalilo, who followed Kamehameha V as king. Then came Bernice Pauahi, who married Hon Charles R Bishop. Our family was represented by Kaliokalani, Kalākaua, and myself, two of the three destined to ascend the throne.”

“From the year 1848 the Royal School began to decline in influence; and within two or three years from that time it was discontinued, the Cooke family entering business with the Castles, forming a mercantile establishment still in existence.”

“From the school of Mr and Mrs Cooke I was sent to that of Rev Mr Beckwith, also one of the American missionaries. This was a day-school, and with it I was better satisfied than with a boarding-school.”

“I was a studious girl; and the acquisition of knowledge has been a passion with me during my whole life, one which has not lost its charm to the present day.  In this respect I was quite different from my sister Bernice.”

“She was one of the most beautiful girls I ever saw; the vision of her loveliness at that time can never be effaced from remembrance; like a striking picture once seen, it is stamped upon memory’s page forever.”

“She married in her eighteenth year. She was betrothed to Prince Lot, a grandchild of Kamehameha the Great; but when Mr Charles R Bishop pressed his suit, my sister smiled on him, and they were married.  It was a happy marriage.”

“At this time I was still living with Pākī and Kōnia, and the house now standing and known as the Arlington Hotel was being erected by the chief for his residence. It was completed in 1851, and occupied by Paki until 1855, when he died.”

“Then my sister and her husband moved to that residence, which still remained my home. It was there that the years of my girlhood were passed, after school-days were over, and the pleasant company we often had in that house will never cease to give interest to the spot.”

The comments in quotes are from Liliʻuokalani from her book “Hawaiʻi’s Story by Hawaiʻi’s Queen, Liliʻuokalani.”

Fast forward … on the afternoon of January 16, 1893, 162 sailors and Marines aboard the USS Boston in Honolulu Harbor came ashore.  The home that Liliʻuokalani was raised in (later known as Arlington Hotel) served as the headquarters for the USS Boston’s landing force (Camp Boston) at the time of the overthrow of the Hawaiian monarchy, January 17, 1893.

Six Active Volcanoes in Hawai‘i

The Hawaiian Islands are at the southeast end of a chain of volcanoes that began to form more than 70 million years ago. Each island is made of one or more volcanoes, which first erupted on the floor of the Pacific Ocean and emerged above sea level only after countless eruptions.

Hawaiʻi sits over a ‘hot spot,’ the Hawaiian hot spot.

It’s one hot spot, but lots of volcanoes have formed over it.  The Islands are above a moving sea floor of the North Pacific Ocean (the Pacific Ocean is mostly floored by a single tectonic plate known as the “Pacific Plate.”)

The Pacific Plate is moving over the layer in the Earth known as the Asthenosphere. This movement takes it to the northwest.  As the plate moves over a fixed spot deeper in the Earth where magma (molten lava) forms, a new volcano can punch through this plate and create an island.

As the plate moves away, the volcano stops erupting and a new one is formed in its place. With time, the volcanoes keep drifting westward and getting older relative to the one active volcano that is over the hot spot.

As they age, the crust that they sit on cools and subsides. This, combined with erosion of the islands, once active volcanism stops, leads to a shrinking of the islands with age and their eventual submergence below the ocean surface.

Each island is made up of at least one primary volcano, although many islands are composites of more than one. The Big Island, for instance, is constructed of 5 major volcanoes: Kilauea, Mauna Loa, Mauna Kea, Hualālai and Kohala (the island is still growing, but is basically about 400,000-years old.)

About 40-million years ago, the Pacific Plate changed direction from north to northwest – so the Emperor Seamounts run more north-south, the Hawaiian Ridge north-westerly.

Midway Island is 27.7-million years old; Meiji Seamount the northern part of the Emperor Seamount (near the end of the Aleutian chain) is about 80-million years old.

All of these are still youngsters, when you look at the perspective, say, of the dinosaurs.  The Islands weren’t even a glimmer in anyone’s eyes when dinosaurs walked the Earth; sixty-five million years ago the last of the non-avian dinosaurs went extinct, after living on Earth for about 165-million years.  (USGS)

If all of Earth time from the very beginning of the dinosaurs to today were compressed into 365 days (1 calendar year), the dinosaurs appeared January 1 and became extinct the third week of September.

Using this same time scale, the Earth would have formed approximately 18.5-years earlier. By comparison, people have been on earth only since December 31 (New Year’s eve.)  (USGS)

While we typically think of and/or hear news reports of eruptions on Kilauea and Maunaloa, presently, the US Geological Survey (USGS) Hawaiian Volcano Observatory  (HVO) monitors the six currently active volcanoes in Hawai‘i.

The Island of Hawai‘i, with four active volcanoes, is liveliest. Between 1912 and 2012, there were nearly 50 Kīlauea eruptions, 12 Mauna Loa eruptions, and one Hualālai intrusion of magma.

Kīlauea, the youngest and most active volcano on the Island of Hawai‘i, erupted almost continuously from 1983 to 2018 at Pu‘u‘ō‘ō and other vents along the volcano’s East Rift Zone. Since then, there have been periodic eruptions in and nearby Halema‘uma‘u crater at the volcano’s summit.

In 2018, Kīlauea experienced the largest lower East Rift Zone eruption and summit collapse in at least 200 years. Several summit eruptions since December 2020 have generated lava lakes that have been slowly filling in the collapsed area, including Halema‘uma‘u crater. About 90 percent of the volcano is covered with lava flows less than 1,100 years in age.

Mauna Loa, the largest volcano on Earth, has erupted 34 times since 1843. An eruption 1984 lasted 22 days and produced lava flows which reached to within about 4.5 miles of Hilo, the largest population center on the Island of Hawai‘i.

The most recent eruption in 2022 lasted two weeks and erupted lava flows that came to within 1.7 miles of the Daniel K Inouye Highway (Saddle Road). Lava flows less than 4,000 years old cover about 90 percent of the volcano.

Hualālai, the third most active volcano on the Island of Hawai‘i, has erupted three times in the past 1,000 years and eight times in the past 1,500 years.

The most recent eruption in 1801 generated a lava flow that reached the ocean and now underlies the Kona International Airport. Lava flows less than 5,000 years old cover about 80 percent of the volcano.

Mauna Kea, the highest volcano on the Island of Hawai‘i, erupted most recently between about 6,000 and 4,500 years ago from at least seven separate summit-area vents, producing lava flows and cinder cones. Glaciers covered parts of the volcano’s summit area during the recent ice ages, the only Hawaiian volcano known to have been glaciated.

Kama‘ehuakanaloa (formerly Lō‘ihi Seamount), the only known active Hawaiian submarine volcano, erupted most recently in 1996 during an earthquake swarm of more than 4,000 events that were recorded by the HVO seismic network. The volcano’s summit is about 3,179 ft below sea level, located 22 miles southeast of the Island of Hawai‘i.

Haleakalā, the only active volcano on the Island of Maui, erupted most recently between about 600 and 400 years ago. In the past 1,000 years, at least 10 eruptions produced lava flows and tephra cones from the rift zone that crosses the volcano from southwest to east and through Haleakalā Crater. (All here is from the US Geological Survey (USGS.))
