Borders onChigmit Mountains and Alaska Range

The Tordrillo Mountains are a small mountain range in the Matanuska-Susitna and Kenai Peninsula Boroughs in the southcentral region of the U.S. state of Alaska. They lie approximately 75 miles (120 km) west-northwest of Anchorage. The range extends approximately 60 miles (97 km) north-south and 35 miles (56 km) east-west. The highest point is Mount Torbert (11,413 feet/3,479 m). On a clear day, they are easily visible from Anchorage.

The Tordrillos are bordered on the south by the Chigmit Mountains, the northernmost extension of the Aleutian Range. (The Tordrillos are sometimes counted as part of the Aleutian Range, but this is not official usage.) On the west and north they meet the southern tip of the Revelation Mountains, part of the Alaska Range, while on the east they fade into the hills and lowlands of southcentral Alaska. The north side of the range feeds the Skwentna River, and the south drains into Chakachamna Lake and the Chakachatna River.

The Tordrillos are primarily a volcanic range, like most of the neighboring Aleutian Range; however some of the peaks (for example, Mount Torbert) are not volcanoes. Mount Spurr, the southernmost peak in the range, had its most recent eruption in June 1992. They are heavily glaciated, partly due to their location near Cook Inlet. Major glaciers include the Capps Glacier, Triumvirate Glacier, Hayes Glacier, and Trimble Glacier.

Despite their proximity to Anchorage, the Tordrillos see little recreational or climbing activity. However Mount Spurr and nearby Crater Peak are regularly visited and monitored by the Alaska Volcano Observatory.

Notes

  1. Cody’s Line
  2. Hayes Volcano is a completely ice-covered volcano, only discovered in 1975, located just to the northeast of Mount Gerdine. It should not be confused with the much more prominent, non-volcanic Mount Hayes in the Alaska Range.

Southcentral Alaska

Southcentral Alaska is the portion of the U.S. state of Alaska consisting of the shorelines and uplands of the central Gulf of Alaska. Most of the population of the state lives in this region, concentrated in and around the city of Anchorage.

Alaska Range North American mountain range

The Alaska Range is a relatively narrow, 400-mile-long (650 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end to the White River in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera.

Aleutian Range

The Aleutian Range is a major mountain range located in southwest Alaska. It extends from Chakachamna Lake to Unimak Island, which is at the tip of the Alaska Peninsula. It includes all of the mountains of the Peninsula. The Aleutian Range is special because of its large number of active volcanoes, which are also part of the larger Aleutian Arc. The mainland part of the range is about 600 miles (1000 km) long. The Aleutian Islands are (geologically) a partially submerged western extension of the range that stretches for another 1,600 km (1000 mi). However the official designation "Aleutian Range" includes only the mainland peaks and the peaks on Unimak Island. The range is almost entirely roadless wilderness. Katmai National Park and Preserve, a large national park within the range, must be reached by boat or plane.

Katmai National Park and Preserve National park in Alaska, United States

Katmai National Park and Preserve is an American national park and preserve in southern Alaska, notable for the Valley of Ten Thousand Smokes and for its brown bears. The park and preserve encompass 4,093,077 acres, which is between the sizes of Connecticut and New Jersey. Most of the national park is a designated wilderness area where all hunting is banned. The park is named after Mount Katmai, its centerpiece stratovolcano. The park is located on the Alaska Peninsula, across from Kodiak Island, with headquarters in nearby King Salmon, about 290 miles (470 km) southwest of Anchorage. The area was first designated a national monument in 1918 to protect the area around the major 1912 volcanic eruption of Novarupta, which formed the Valley of Ten Thousand Smokes, a 40-square-mile (100 km2), 100-to-700-foot-deep pyroclastic flow. The park includes as many as 18 individual volcanoes, seven of which have been active since 1900.

Lake Clark National Park and Preserve National park in southwest Alaska, United States

Lake Clark National Park and Preserve is an American national park in southwest Alaska, about 100 miles (160 km) southwest of Anchorage. The park was first proclaimed a national monument in 1978, then established as a national park and preserve in 1980 by the Alaska National Interest Lands Conservation Act. The park includes many streams and lakes vital to the Bristol Bay salmon fishery, including its namesake Lake Clark. A wide variety of recreational activities may be pursued in the park and preserve year-round. The park protects rainforests along the coastline of Cook Inlet, alpine tundra, glaciers, glacial lakes, major salmon-bearing rivers, and two volcanoes, Mount Redoubt and Mount Iliamna. Mount Redoubt is active, erupting in 1989 and 2009. The wide variety of ecosystems in the park mean that virtually all major Alaskan animals, terrestrial and marine, may be seen in and around the park. Salmon, particularly sockeye salmon, play a major role in the ecosystem and the local economy. The Kvichak River is the world's most productive watershed for sockeye salmon. Large populations of brown bears are attracted to feed on the spawning salmon in the Kijik River and at Silver Salmon Creek. Bear watching is a common activity in the park.

Mount Spurr

Mount Spurr is a stratovolcano in the Aleutian Arc of Alaska, named after United States Geological Survey geologist and explorer Josiah Edward Spurr, who led an expedition to the area in 1898. The Alaska Volcano Observatory (AVO) currently rates Mount Spurr as Level of Concern Color Code Green. The mountain is known aboriginally by the Dena'ina Athabascan name K'idazq'eni, literally 'that which is burning inside'.

Mount Redoubt Volcanic cone in the United States

Redoubt Volcano, or Mount Redoubt, is an active stratovolcano in the largely volcanic Aleutian Range of the U.S. state of Alaska. Located at the head of the Chigmit Mountains subrange in Lake Clark National Park and Preserve, the mountain is just west of Cook Inlet, in the Kenai Peninsula Borough about 110 miles (180 km) southwest of Anchorage. At 10,197 feet (3,108 m), in just over 5 miles (8 km) Mount Redoubt attains 9,150 feet (2,700 m) of prominence over its surrounding terrain. It is the highest summit in the Aleutian Range. In 1976, Redoubt Volcano was designated as a National Natural Landmark by the National Park Service.

Mount Shishaldin

Mount Shishaldin is a moderately active volcano on Unimak Island in the Aleutian Islands chain of Alaska. It is the highest mountain peak of the Aleutian Islands. The most symmetrical cone-shaped glacier-clad large mountain on Earth, the volcano's topographic contour lines are nearly perfect circles above 6,500 feet (1,981 m). The lower north and south slopes are somewhat steeper than the lower eastern and western slopes. The volcano is the westernmost of three large stratovolcanoes along an east–west line in the eastern half of Unimak Island.

Mount Sanford (Alaska)

Mount Sanford is a shield volcano in the Wrangell Volcanic Field, in eastern Alaska near the Copper River. It is the sixth highest mountain in the United States and the third highest volcano behind Mount Bona and Mount Blackburn. The south face of the volcano, at the head of the Sanford Glacier, rises 8,000 feet (2,400 m) in 1 mile (1,600 m) resulting in one of the steepest gradients in North America.

Makushin Volcano

The Makushin Volcano is an ice-covered stratovolcano located on Unalaska Island in the Aleutian Islands of the U.S. state of Alaska. With an elevation of 2,036 meters (6,680 ft), its summit is the highest point on the island. Makushin is one of the most active among the 52 historically active volcanoes of Alaska. It has erupted at least two dozen times over the past several thousand years, with the last eruption occurring in 1995.

Mount Carlisle

Mount Carlisle is a stratovolcano in Alaska which forms part of the 5 mile (8 km) wide Carlisle Island, one of the Islands of Four Mountains which, in turn, form part of the central Aleutian Islands.

Mount Iliamna

Mount Iliamna is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.

Mount Wrangell

Mount Wrangell, in Ahtna K’ełt’aeni or K’ełedi when erupting, is a massive shield volcano located in Wrangell-St. Elias National Park and Preserve in southeastern Alaska, United States. The shield rises over 12,000 feet (3,700 m) above the Copper River to its southwest. Its volume is over 220 cubic miles (920 km3), making it more than twice as massive as Mount Shasta in California, the largest stratovolcano by volume in the Cascades. It is part of the Wrangell Volcanic Field, which extends for more than 250 kilometers (160 mi) across Southcentral Alaska into the Yukon Territory, and has an eruptive history spanning the time from Pleistocene to Holocene.

Hayes Volcano

Hayes Volcano is a stratovolcano in southwestern Matanuska-Susitna Borough, Alaska, 135 km northwest of Anchorage, that was not discovered until 1975. It is responsible for a series of six major tephra layers in the Cook Inlet region of Alaska. Hayes was mostly destroyed by at least six catastrophic eruptions between 3,400 and 3,800 years ago, and the average volume of these eruptions was 2.4 cubic km. In comparison, the volume of the May 18, 1980 eruption of Mount St. Helens was about 1 cubic km. The eruptions of Hayes Volcano during that time were the most voluminous Holocene eruptions to have occurred in the Cook Inlet region. There is currently no fumarolic activity present. The last eruption of Hayes Volcano occurred roughly 1,200 years ago. It is named after the adjacent Hayes Glacier.

Mount Torbert Mountain in the United States of America

Mount Torbert is the highest point of the Tordrillo Mountains, a small, primarily volcanic range, northwest of Anchorage, Alaska. It is a heavily glaciated peak, and is not itself a volcano, although nearby Mount Spurr and Crater Peak are active volcanoes.

Gareloi Volcano Stratovolcano in the Aleutian Islands of Alaska, U.S.

The Gareloi Volcano is a stratovolcano in the Aleutian Islands of Alaska, United States, about 1,259 miles (2,026 km) from Anchorage. Gareloi is located on Gareloi Island, and comprises most of its land mass. The island also has two small glaciers which protrude to the northwest and southeast.

Fisher Caldera, also known as Mount Fisher and Fisher Volcano, is a large volcanic caldera, measuring about 6.8 miles (11 km) by 11 miles (18 km), located on Unimak Island in the Aleutian Islands of Alaska. Formed by the destructive eruption of an andesitic stratovolcano about 9,100 years ago, it contains three crater lakes, one 2 miles (3.2 km) wide and two others about 1.5 miles (2.4 km) wide. Small peaks rising 2,000 feet (600 m) and 2,031 feet (619 m) are also present in the caldera. Fisher Caldera is located just 13 miles (21 km) from the Mount Westdahl volcano.

Mount Nagishlamina

Mount Nagishlamina is an 11,068-foot glaciated mountain summit located in the Tordrillo Mountains of the Alaska Range, in the US state of Alaska. The mountain is situated 90 mi (145 km) west of Anchorage, 7.4 mi (12 km) northwest of Mount Spurr, and 1.9 mi (3 km) southeast of Mount Torbert, which is the nearest higher neighbor. It is the fifth-highest peak in the Tordrillo Mountains, a subset of the Alaska Range. The mountain takes its Denaʼina language name from the Nagishlamina River which drains the west side of the peak. Mount Nagishlamina's name was in use by local mountaineers since the 1970s, and was officially adopted in 1999 by the U.S. Board on Geographic Names. This geographic feature was likely the highest unclimbed peak in the United States at the time of its first ascent in 1989 by Dave Johnston.
