Mount Dech is a 7,475-foot-elevation (2,278-meter) mountain summit in Alaska.
Mount Dech is the third-highest peak in the Takhinsha Mountains which are a subrange of the Saint Elias Mountains. [2] It is located 14 miles (23 km) southwest of Haines on the northern boundary of Glacier Bay National Park and Preserve. Precipitation runoff and glacial meltwater from the mountain's north slope drains to the Chilkat River, whereas the south slope drains to Glacier Bay. Although modest in elevation, topographic relief is significant as the summit rises 3,500 feet (1,067 meters) above the Garrison Glacier in one mile (1.6 km). The mountain was named by a group of climbers led by Lawrence E. Nielsen who made the first ascent of the summit on June 19, 1966. [1] The peak's toponym is a Tlingit word meaning "two." [1] The mountain's toponym has not been officially adopted by the United States Board on Geographic Names, and it will remain unofficial as long as the USGS policy of not adopting new toponyms in designated wilderness areas remains in effect.
According to the Köppen climate classification system, Mount Dech is located in a tundra climate zone with cold, snowy winters, and cool summers. [4] Weather systems coming off the Gulf of Alaska are forced upwards by the Takhinsha Mountains (orographic lift), causing heavy precipitation in the form of rainfall and snowfall. Winter temperatures can drop to 0 °F with wind chill factors below −10 °F. This climate supports the Bertha, Casement, and Garrison glaciers surrounding the peak.
Mount Cooper is a 6780-foot (2067-meter) mountain summit located in the Fairweather Range of the Saint Elias Mountains, in southeast Alaska. The peak is situated in Glacier Bay National Park and Preserve at the entrance to Johns Hopkins Inlet, 100 mi (161 km) northwest of Juneau, and 5.6 mi (9 km) northeast of Mount Abbe, which is the nearest higher peak. Although modest in elevation, relief is significant since the mountain rises up from tidewater in less than two miles. Mount Cooper can be seen from Johns Hopkins Inlet which is a popular destination for cruise ships. The mountain's name was proposed in the 1950s for William Skinner Cooper (1884-1978), a plant ecologist who performed vegetation-glacier relationship studies in the Glacier Bay area, and was chairman of the committee of scientists which proposed establishing Glacier Bay National Monument. The mountain's name was officially adopted in 1980 by the United States Geological Survey following Cooper's death. The months May through June offer the most favorable weather for climbing Mount Cooper.
Awesome Peak is an 8,645-foot-elevation (2,635-meter) mountain summit located 35 miles (56 km) east-northeast of Palmer, in the northern Chugach Mountains of Alaska. This peak of the Matanuska Valley is set midway between Anchorage and Glennallen, near mile 90 of the Glenn Highway. It is situated 15 miles (24 km) west of Matanuska Glacier and 3.7 mi (6 km) southwest of Amulet Peak. Precipitation runoff from the mountain drains into Monument and Coal creeks, which are tributaries of the Matanuska River. Topographic relief is significant as the summit rises 5,650 feet above Coal Creek in 3.75 miles (6 km) and 4,650 feet above Monument Creek in 1.9 mile (3 km). This mountain's toponym has not been officially adopted by the United States Board on Geographic Names, so it is only marked as "8645" on USGS maps.
Mount Kiev is a 7,775-foot-elevation (2,370-meter) mountain summit located in Alaska, United States.
Mount Shouplina is an 8,531-foot-elevation (2,600-meter) mountain summit located 18 miles (29 km) north-northwest of Valdez in the U.S. state of Alaska. This remote glaciated mountain is set in the Chugach Mountains on land managed by Chugach National Forest. Precipitation runoff from the mountain drains south to Prince William Sound and north to Tazlina Lake → Tazlina River → Copper River. Topographic relief is significant as the summit rises 2,100 feet (640 m) above the East Branch Columbia Glacier in 0.4 mile (0.64 km). The first ascent of the summit was made in 1985 by John Weiland, Matt Kinney, and Bob Shelton. The mountain was named in 1959 by mountaineer Lawrence E. Nielsen and the toponym was officially adopted in 1965 by the U.S. Board on Geographic Names. The word "Shouplina" is a portmanteau blending the names of the Shoup Glacier and Tazlina Glacier which flow from this mountain's south and north slopes respectively.
Lindita Peak is a 7,910-foot-elevation (2,411-meter) mountain summit located 17 miles (27 km) north-northwest of Valdez in the U.S. state of Alaska. Lindita is the highest peak at the head of the Tazlina Glacier when viewed from the Glenn Highway at Mile 156 near the Tazlina Glacier Lodge. This remote glaciated mountain is set in the Chugach Mountains on land managed by Chugach National Forest. Precipitation runoff from the mountain drains south to Prince William Sound and north to Tazlina Lake → Tazlina River → Copper River. Topographic relief is significant as the summit rises 2,400 feet (732 m) above the East Branch of the Columbia Glacier in 0.4 mile (0.64 km). The mountain's name Lindita, meaning "little beauty" in Spanish, was applied in 1955 by mountaineer and glaciologist Lawrence E. Nielsen (1917–1992), and the toponym was officially adopted in 1965 by the U.S. Board on Geographic Names. The first ascent of the summit was made on July 1, 1977, by Lawrence E. Nielsen, Halford Joiner, Tom Lamb, and Dr. Randall Travis via the northeast face and the north-facing knife-edged ridge from the Tazlina Glacier.
Tazcol Peak is a 7,850-foot-elevation (2,393-meter) mountain summit located 18 miles (29 km) north-northwest of Valdez in the U.S. state of Alaska. This remote glaciated mountain is set in the Chugach Mountains on land managed by Chugach National Forest. Precipitation runoff from the mountain drains south to Prince William Sound and north to Tazlina Lake → Tazlina River → Copper River. Topographic relief is significant as the summit rises 4,350 feet (1,326 m) above the East Branch of the Columbia Glacier in 1.4 mile (2.25 km). The peak's name was applied in 1959 by mountaineer and glaciologist Lawrence E. Nielsen (1917–1992), and the toponym was officially adopted in 1965 by the U.S. Board on Geographic Names. The word "Tazcol" is a portmanteau blending the names of the Tazlina Glacier and Columbia Glacier which flow from this mountain's north and south slopes respectively.
