[14] Subglacial eruptions built cinder cones during the Mākanaka glaciation,[21] most of which were heavily gouged by glacial action. Donald Thomas, director of the University of Hawaiʻi's Center for the Study of Active Volcanoes believes one reason to continue study of the aquifers is due to use and occupancy of the higher elevation areas, stating: "Nearly all of these activities depend on the availability of potable water that, in most cases, must be trucked to the Saddle from Waimea or Hilo — an inefficient and expensive process that consumes a substantial quantity of our scarce liquid fuels. While the summit is often covered with snow, the air is extremely dry. The lake is very small and shallow, with a surface area of 0.73 ha (1.80 acres) and a depth of 3 m (10 ft). [87][88] Between 5,000 and 6,000 people visit the summit of Mauna Kea each year, and to help ensure safety, and protect the integrity of the mountain, a ranger program was implemented in 2001. This plan was further revised to address concern expressed in the Hawaiian community that a lack of respect was being shown toward the cultural value the mountain embodied to the region's indigenous people. In the early 19th century, the earliest notable recorded ascents of Mauna Kea included the following: In the late 19th and early 20th centuries trails were formed, often by the movement of game herds, that could be traveled on horseback. [3][8][9] Jefferies had gained his reputation through observations at Sacramento Peak Observatory. [68][69] The TMT was approved in April 2013. The Mauna Kea Access Road is paved up to the Center at 2,804 m (9,199 ft). Hawaiʻi Department of Land and Natural Resources, Palila v.

While the land was partitioned no money was allocated for the building of the fence. [7]:56, The Audubon Society objected to further development on Mauna Kea over concerns to habitat of the endangered Palila, a species endemic to only specific parts of this mountain. [53] The feral animals were almost eradicated, and numbered a few hundred in the 1950s. [43], The largest threat to the ecosystem is grazing by feral sheep, cattle (Bos primigenius),[53] and goats (Capra hircus) introduced to the island in the late 18th century. The vertical distance between the foot of the mountain and the summit is over 10,000 meters. Brakes often overheat on the way down and there is no fuel available on Mauna Kea. Higher up, feral animals that escaped from ranches found refuge in, and damaged extensively, Mauna Kea's native māmane–naio forest. In 1973, Canada and France agreed to build the 3.6 m CFHT on Mauna Kea. [75] After several halts, the project has been voluntarily postponed. Using town hall meetings, Jefferies was able to overcome opposition by weighing the economic advantage and prestige the island would receive. The proposal was for a two-meter telescope to serve both the needs of NASA and the university. [16], Lava flows from Mauna Kea overlapped in complex layers with those of its neighbors during its growth. [9] Similar deposits probably existed on Mauna Loa, but have been covered by later lava flows. Although not likely in the next few centuries, such an eruption would probably result in little loss of life but significant damage to infrastructure. [25] One study reported that around a third of visitors and two thirds of professional astronomers working on the mountain have experienced symptoms of acute altitude sickness;[85] visitors traveling up the volcano's flanks are advised to stop for at least half an hour and preferably longer at the visitor center to acclimate to the higher elevation. [76] The Supreme Court of Hawaiʻi approved the resumption of construction on 31 October 2018. Because of its elevation, Mauna Kea has the greatest diversity of biotic ecosystems anywhere in the Hawaiian archipelago. [45] Birdwatching is also common at lower levels on the mountain. Accommodations for research astronomers are located at the Onizuka Center for International Astronomy (often called Hale Pōhaku), 7 miles (11 km) by unpaved steep road from the summit at 9,300 feet (2,800 m) above sea level. [14] Small gullies etch the summit, formed by rain- and snow-fed streams that flow only during winter melt and rain showers. [14] The Hawaii island volcanoes are the most recent evidence of this process that, over 70 million years, has created the 6,000 km (3,700 mi)-long Hawaiian Ridge–Emperor seamount chain. [4] These cones are the most recent eruptive centers of Mauna Kea. A public hunting program removed many of the feral animals,[47] at least temporarily. Their construction on a landscape considered sacred by Native Hawaiians continues to be a topic of debate to this day. An intense three-way competition for NASA funds to construct a large telescope began between Kuiper, Harvard University, and the University of Hawaiʻi (UH), which only had experience in solar astronomy. [25][60][61] The arid conditions are important for submillimeter and infrared astronomy for this region of the electromagnetic spectrum. After studying photos for NASA's Apollo program that contained greater detail than any ground-based telescope, Gerard Kuiper began seeking an arid site for infrared studies. Despite many references to burial around Mauna Kea in Hawaiian oral history, few sites have been confirmed. As we drive up the mountain, we learn about island geography, geology and natural history. The 1982 plan was replaced in 2000 by an extension designed to serve until 2020: it instituted an Office of Mauna Kea Management,[13] designated 525 acres (212 ha) for astronomy, and shifted the remaining 10,763 acres (4,356 ha) to "natural and cultural preservation". The closely related Nysius aa lives on Mauna Loa.

Mauna Kea's summit was encompassed in the ahupuaʻa of Kaʻohe, with part of its eastern slope reaching into the nearby Humuʻula. However, an influx of local hunters led to the feral species being valued as game animals, and in 1959 the Hawaiʻi Department of Land and Natural Resources, the governing body in charge of conservation and land use management, changed its policy to a sustained-control program designed to facilitate the sport. Kama'āina Observatory Experience: The Kama‘āina Observatory Experience is currently suspended due to COVID 19.When it is in operation is a monthly community event that welcomes Hawai‘i residents to the science reserve atop Maunakea to see world-class telescopes and learn about the cultural and environmental importance of the mountain. [52], The forested zone on the volcano, at an elevation of 2,000–3,000 m (6,600–9,800 ft), is dominated by māmane (Sophora chrysophylla) and naio (Myoporum sandwicense), both endemic tree species, and is thus known as māmane–naio forest. With an additional land grant in 1845, Parker established Parker Ranch on the northern slope of Mauna Kea, a large cattle ranch that is still in operation today. The seeing statistics show that Mauna Kea is the best site in terms of optical and infrared image quality; for example, the CFHT site has a median seeing of 0.43 arcseconds. [67] A planned new telescope, the Thirty Meter Telescope (TMT), has attracted controversy and protests. [59] Parts of the reserve show the effect of agriculture on the native ecosystem,[47] as much of the land in the upper part of the reserve is abandoned farmland. Site testing by Kuiper's assistant Alika Herring in 1964 confirmed the summit's outstanding suitability. It is strongly recommended to use a four-wheel drive vehicle to drive all the way to the top. They can survive at extreme elevations of up to 4,200 m (13,780 ft)[51] because of natural antifreeze in their blood. This culminated in funds being awarded to the "upstart" UH proposal. In total, there are twelve facilities housing thirteen telescopes[21] at or around the summit of Mauna Kea. The 1982 plan was replaced in 2000 by an extension designed to serve until 2020: it instituted an Office of Mauna Kea Management,[61] designated 525 acres (212 ha) for astronomy, and shifted the remaining 10,763 acres (4,356 ha) to "natural and cultural preservation". 2601", "Mauna Kea: Hawaiian Volcano Observatory", "Mauna Loa, Hawaiian Volcano Observatory, Summary", "The Emperor and Hawaiian Volcanic Chains: How well do they fit the plume hypothesis? The 108,863-acre (44,055 ha) base extends from the volcano's lower flanks to 2,070 m (6,790 ft) elevation, on state land leased to the US Army since 1956. [10] [32], The first Ancient Hawaiians to arrive on Hawaiʻi island lived along the shores, where food and water were plentiful. The location is near ideal because of its dark skies from lack of light pollution, good astronomical seeing, low humidity, high elevation of 4,205 meters (13,796 ft), position above most of the water vapor in the atmosphere, clean air, good weather and low latitude location.[2]. [18] They are covered by the oldest exposed rock strata on Mauna Kea, the post-shield alkali basalts of the Hāmākua Volcanics, which erupted between 250,000 and 70–65,000 years ago. Banko, Paul et al. [29], A number of the telescopes sustained minor damage during the October 15, 2006 Kiholo Bay earthquake and aftershocks. Safety tips for visiting MaunaKea The MaunaKea summit at an elevation of 13,796 feet (4205 meters) is an extreme environment with an atmospheric pressure 40 percent lower compared to sea level. sandwicense), a highly endangered endemic plant species that thrives in Mauna Kea's high elevation cinder deserts. Bird species hunted included the ʻuaʻu (Pterodroma sandwichensis), nēnē (Branta sandvicensis), and palila (Loxioides bailleui). [28], No artesian water was known on the island of Hawaiʻi until 1993 when drilling by the University of Hawaiʻi tapped an artesian aquifer more than 300 m (980 ft) below sea level, that extended more than 100 m (330 ft) of the borehole's total depth. [39], Around AD 1100, natives established adze quarries high up on Mauna Kea to extract the uniquely dense basalt (generated by the quick cooling of lava flows meeting glacial ice during subglacial eruptions) to make tools. Ancient Hawaiians brought foreign plants and animals, and their arrival was associated with increased rates of erosion. The prevailing lowland forest ecosystem was transformed from forest to grassland; some of this change was caused by the use of fire, but the prevailing cause of forest ecosystem collapse and avian extinction on Hawaiʻi appears to have been the introduction of the Polynesian (or Pacific) rat. [43] These ecosystems can be roughly divided into three sections by elevation: alpine–subalpine, montane, and basal forest. [31], Despite its dormancy, Mauna Kea is expected to erupt again. [9], Mauna Kea is the only Hawaiian volcano with distinct evidence of glaciation. UH has held the master lease to manage Mauna Kea since 1968. On July 18, 2019, an online petition titled "Impeach Governor David Ige" had been posted to Change.org and has currently gathered over 62,562 signatures.[79]. [14][19] These changes in lava composition accompanied the slow reduction of the supply of magma to the summit, which led to weaker eruptions that then gave way to isolated episodes associated with volcanic dormancy. [6] It is about a million years old, and has thus passed the most active shield stage of life hundreds of thousands of years ago. A lack of soil also retards root growth, makes it difficult to absorb nutrients from the ground, and gives the area a very low water retention capacity. It is an ideal location for submillimeter, infrared and optical observations. [11] However, local organizations started to raise concerns about the environmental impact of the observatory. CSO, UKIRT, and Hoku Kea are scheduled for decommissioning as part of the Mauna Kea Comprehensive Management Plan. [26], Wēkiu bugs feed on dead insect carcasses that drift up Mauna Kea on the wind and settle on snow banks. Mauna Kea Beach Hotel is an oceanfront property residing along the beautiful Kohala Coast. [48], The summit of Mauna Kea lies above the tree line, and consists of mostly lava rock and alpine tundra. In its current post-shield state, its lava is more viscous, resulting in a steeper profile. Jefferies would build a 2.24 meter telescope with the State of HawaiÊ»i agreeing to build a reliable, all weather roadway to the summit. Hawaiian lava types are typically permeable, preventing lake formation due to infiltration. Despite opposition from conservationists the plan was put into action. [26] A "Save Mauna Kea" movement was inspired by the proliferation of telescopes, with opposition believing development of the mountain to be sacrilegious. Camera is located in the Smithsonian Astrophysical Observatory's Submillimeter Array on Mauna Kea See the South Pole! Its peak is 4,207.3 m (13,803 ft) above sea level, making it the highest point in the state of Hawaiʻi. [66] The multi-telescope "outrigger" proposed in 2006 was eventually canceled. Their conservation status is unclear, but the species is no longer a candidate for the Endangered Species List; studies on the welfare of the species began in 1980. It stands 4,207.3 m (13,803 ft) above sea level,[11] about 38 m (125 ft) higher than its neighbor Mauna Loa,[12] and is the highest point in the state of Hawaii. [34], In 1793, cattle were brought by George Vancouver as a tribute to King Kamehameha I. [33] The mountain's plentiful forest provided plants and animals for food and raw materials for shelter. There are 15 threatened and endangered plants, three endangered birds, and one endangered bat species in the area.
