The Wrangell Mountains are a high mountain range of eastern Alaska in the United States. Much of the range is included in Wrangell-Saint Elias National Park and Preserve. The Wrangell Mountains are almost entirely volcanic in origin, and they include the second and third highest volcanoes in the United States, Mount Blackburn and Mount Sanford. The range takes its name from Mount Wrangell, which is one of the largest andesite shield volcanoes in the world, and also the only presently active volcano in the range. The Wrangell Mountains comprise most of the Wrangell Volcanic Field, which also extends into the neighboring Saint Elias Mountains and the Yukon Territory in Canada.
Glacier Peak or Dakobed is the most isolated of the five major stratovolcanoes of the Cascade Volcanic Arc in the U.S state of Washington. Located in the Glacier Peak Wilderness in Mount Baker–Snoqualmie National Forest, the volcano is visible from the west in Seattle, and from the north in the higher areas of eastern suburbs of Vancouver such as Coquitlam, New Westminster and Port Coquitlam. The volcano is the fourth tallest peak in Washington state, and not as much is known about it compared to other volcanoes in the area. Local Native Americans have recognized Glacier Peak and other Washington volcanoes in their histories and stories. When American explorers reached the region, they learned basic information about surrounding landforms, but did not initially understand that Glacier Peak was a volcano. Positioned in Snohomish County, the volcano is only 70 miles (110 km) northeast of downtown Seattle. From locations in northern Seattle and northward, Glacier Peak is closer than the more famous Mount Rainier (Tahoma), but as Glacier Peak is set farther into the Cascades and almost 4,000 feet (1,200 m) shorter, it is much less noticeable than Mount Rainier.
The Saint Elias Mountains are a subgroup of the Pacific Coast Ranges, located in southeastern Alaska in the United States, Southwestern Yukon and the very far northwestern part of British Columbia in Canada. The range spans Wrangell-St. Elias National Park and Preserve in the United States and Kluane National Park and Reserve in Canada and includes all of Glacier Bay National Park in Alaska. In Alaska, the range includes parts of the city/borough of Yakutat and the Hoonah-Angoon and Valdez-Cordova census areas.
Wrangell–St. Elias National Park and Preserve is a United States national park and preserve in south central Alaska. The park, the largest in the United States, covers the Wrangell Mountains and a large portion of the Saint Elias Mountains, which include most of the highest peaks in the United States and Canada, yet are within 10 miles (16 km) of tidewater, one of the highest reliefs in the world. The park's high point is Mount Saint Elias at 18,008 feet (5,489 m), the second tallest mountain in both the United States and Canada. The park has been shaped by the competing forces of volcanism and glaciation, with its tall mountains uplifted by plate tectonics. Mount Wrangell and Mount Churchill are among major volcanos in these ranges. The park's glacial features include Malaspina Glacier, the largest piedmont glacier in North America, Hubbard Glacier, the longest tidewater glacier in Alaska, and Nabesna Glacier, the world's longest valley glacier. The Bagley Icefield covers much of the park's interior, which includes 60% of the permanently ice-covered terrain in Alaska. At the center of the park and preserve, the boomtown of Kennecott exploited one of the world's richest deposits of copper from 1903 to 1938. The abandoned mine buildings and mills comprise a National Historic Landmark district.
The Wrangell Volcanic Field is a volcanic field stretching from eastern Alaska in the United States to the southwestern Yukon Territory in Canada. The field includes the four highest volcanoes in the United States, Mount Bona, Mount Blackburn, Mount Sanford, and Mount Churchill, all of which exceed 15,000 ft in elevation. It formed as a result of subduction of the Pacific Plate beneath the North American Plate at the easternmost end of the Aleutian Trench[3].
Mount Blackburn is the highest peak in the Wrangell Mountains of Alaska in the United States. It is the fifth-highest peak in the United States and the twelfth-highest peak in North America. The mountain is an old, eroded shield volcano, the second-highest volcano in the U.S. behind Mount Bona and the fifth-highest in North America. It was named in 1885 by Lt. Henry T. Allen of the U.S. Army after Joseph Clay Stiles Blackburn, a U.S. senator from Kentucky. It is located in the heart of Wrangell – St. Elias National Park, the largest national park in the country.
Nabesna Glacier is a glacier in the U.S. state of Alaska. Fed by deep snowfall in the Wrangell Mountains, the 53 mile (85 km) long Nabesna is the longest valley glacier in North America and the world's longest interior valley glacier.
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 Wrangell, 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 Mountains as well as the Wrangell Volcanic Field, which extends for more than 250 kilometers (160 mi) across Southcentral Alaska into the Yukon Territory in Canada, and has an eruptive history spanning the time from Pleistocene to Holocene.
Mount Augusta, also designated Boundary Peak 183, is a high peak in the US state of Alaska and the Canadian territory of Yukon. It lies about 25 km (16 mi) south of Mount Logan and 25 km east of Mount Saint Elias, respectively the first and second highest mountains in Canada. Mount Augusta forms the eastern end of the long ridge of which Mount Saint Elias is the center and highest point.
Mount Bona is one of the major mountains of the Saint Elias Mountains in eastern Alaska, and is the fifth-highest independent peak in the United States. It is either the tenth- or eleventh-highest peak in North America. Mount Bona and its adjacent neighbor Mount Churchill are both large ice-covered stratovolcanoes. Bona has the distinction of being the highest volcano in the United States and the fourth-highest in North America, outranked only by the three highest Mexican volcanoes, Pico de Orizaba, Popocatépetl, and Iztaccíhuatl. Its summit is a small stratovolcano on top of a high platform of sedimentary rocks.
Mount Bear is a high, glaciated peak in the Saint Elias Mountains of Alaska. It lies within Wrangell-Saint Elias National Park, about 4 miles (6.4 km) west of the Yukon border. The Barnard Glacier flows from its southwest slopes, while the Klutlan Glacier lies to the north. Its principal claim to fame is that it is a fourteener, and in fact one of the highest 20 peaks in the United States.
Mount Miller is an isolated peak of the Saint Elias Mountains in Alaska, United States. It is notable for its position among spectacular icefields, its distance from any inhabited place, and its large rise above local terrain. It is over 65 miles (105 km) from McCarthy, the nearest habitation, and over 105 miles (169 km) away from Yakutat, the nearest significant town. Exemplifying the size of the mountain, the south flank rises 9,000 feet (2,700 m) above the Duktoth River valley to the south in approximately 9 horizontal miles (14 km).
Mount Drum is a stratovolcano in the Wrangell Mountains of east-central Alaska in the United States. It is located at the extreme western end of the Wrangells, 18 miles (29 km) west-southwest of Mount Sanford and the same distance west-northwest of Mount Wrangell. It lies just inside the western boundary of Wrangell-Saint Elias National Park and Preserve and is 25 miles (40 km) east of the Copper River.
Atna Peaks is an eroded stratovolcano or shield volcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell–Saint Elias National Park about 6 miles (9.7 km) east of Mount Blackburn, the second-highest volcano in the United States, and just south of the massive Nabesna Glacier. Because the mountain is almost entirely covered in glaciers, no geological studies have been done, but published references state and the geological map shows that the mountain is an old eroded volcanic edifice.
Regal Mountain is an eroded stratovolcano or shield volcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell-Saint Elias National Park about 19 mi (31 km) east of Mount Blackburn, the second highest volcano in the United States, and southeast of the massive Nabesna Glacier. Regal Mountain is the third highest thirteener in Alaska, ranking just behind its neighbor, Atna Peaks. Because the mountain is almost entirely covered in glaciers, no geological studies have been done, but published references state and the geological map shows that the mountain is an old eroded volcanic edifice.
Mount Jarvis is an eroded shield volcano and stratovolcano in the Wrangell Mountains of eastern Alaska. It is located in Wrangell-Saint Elias National Park about 10 miles (16 km) east of the summit of Mount Wrangell. The mountain sits at the northeastern edge of the massive ice-covered shield of Wrangell, rising nearly 5,000 feet (1,500 m) above it in a spectacular series of cliffs and icefalls.
Mount Huxley is a 12,216-foot glaciated mountain summit located in the Saint Elias Mountains of Wrangell-St. Elias National Park and Preserve, in the U.S. state of Alaska. The remote peak is situated 75 mi (121 km) northwest of Yakutat, and 8.7 mi (14 km) west-northwest of Mount Saint Elias. The peak rises above the Columbus Glacier and Bagley Icefield to its north, the Tyndall Glacier to the south, and the Yahtse Glacier to the west. Precipitation runoff from the mountain drains into the Gulf of Alaska. The mountain was named in 1886 by English mountaineer Harold Ward Topham for Thomas Henry Huxley (1825-1895), an English biologist. The mountain was officially named Huxley Peak in 1917, but the name was officially changed to Mount Huxley in 1968 by the U.S. Board on Geographic Names. The first ascent of the peak was made June 9, 1996 by Paul Claus who landed his plane at 11,500 feet elevation on the western flank and climbed the remaining distance to the summit. The second ascent of Mt. Huxley, and first complete ascent from base to summit, was made in June 2018 by Scott Peters, Andrew Peter, and Ben Iwrey starting from the Columbus Glacier.
