Snowden Mountain is a 6,420-foot-elevation (1,957 meter) mountain summit located in the Brooks Range, in the U.S. state of Alaska.

Contents

Description

The mountain is situated 13 miles north of Sukakpak Mountain, 100 miles north of the Arctic Circle, and 200 miles north-northwest of Fairbanks. The peak lies along the east side of the Dietrich River valley, and can be seen from the Dalton Highway which traverses the valley. Topographic relief is significant as the summit rises 4,700 feet (1,432 meters) above the river in two miles.

The peak is set in the Snowden Mountain Area of Critical Environmental Concern, which is managed by the Bureau of Land Management. This ACEC is extremely rugged and was established to protect Dall sheep habitat on the southern slope of the Brooks Range.

The peak is named in association with Snowden Creek heading on its southeast slope, which in turn was named in 1939 by Robert Marshall for his Eskimo friend and hunting partner, Nutirwik, also known as Harry Snowden. [5] The name has been officially adopted by the U.S. Board on Geographic Names.

Climate

Based on the Köppen climate classification, Snowden Mountain is located in a subarctic climate zone with long, cold, winters, and short, cool summers. [6] Winter temperatures can drop below −30 °F with wind chill factors below −50 °F. Precipitation runoff from the mountain drains west into the Dietrich River. The months June through August offer the most favorable weather for viewing and climbing.

Mount Hayes Mountain in Alaska, United States

Mount Hayes is the highest mountain in the eastern Alaska Range, in the U.S. state of Alaska. Despite not being a fourteener, it is one of the largest peaks in the United States in terms of rise above local terrain. For example, the Northeast Face rises 8,000 feet (2,440 m) in approximately 2 miles (3.2 km). This large vertical relief contributes to Mount Hayes being the 51st most topographically prominent peak in the world.

Mount Abdallah

Mount Abdallah is a prominent 6,210-foot (1,893-meter) mountain summit located in the Alsek Ranges of the Saint Elias Mountains, in southeast Alaska. The mountain is situated in Glacier Bay National Park and Preserve, as the highest point between Tarr Inlet and Rendu Inlet, 93 mi (150 km) northwest of Juneau, and 10.5 mi (17 km) southeast of Mount Barnard, which is the nearest higher peak. Although modest in elevation, relief is significant since the mountain rises up from tidewater in less than three miles. The mountain was named in 1892 by Harry Fielding Reid, an American geophysicist, who in 1892 hired a small crew of men for an expedition to study glaciology in Glacier Bay. There is no record of who Reid named this mountain for, but a member of his expeditionary crew who accompanied him might be a possibility. The months May through June offer the most favorable weather for viewing Mount Abdallah. Weather permitting, Mount Abdallah can be seen from Glacier Bay, which is a popular destination for cruise ships.

Mount La Perouse Glaciated mountain summit in Alaska, US

Mount La Perouse is a 10,728-foot glaciated mountain summit located in the Fairweather Range of the Saint Elias Mountains, in southeast Alaska, United States. The peak is situated in Glacier Bay National Park, 4 mi (6 km) southeast of Mount Dagelet, 7.6 mi (12 km) south-southeast of Mount Crillon which is the nearest higher peak, and 28.6 mi (46 km) southeast of Mount Fairweather, which is the highest peak in the Fairweather Range. Topographic relief is significant as the mountain rises up from tidewater in less than nine miles. The mountain was named in 1874 by William Healey Dall of the U.S. Geological Survey, for Jean-François de Galaup, comte de Lapérouse (1741-1788), a French navigator who explored this coastal area in 1786. The first ascent of the peak was made in 1953 by USGS party consisting of James Seitz, Karl Stauffer, Rowland Tabor, Rolland Reid, and Paul Bowen. On February 16, 2014, a colossal 68 million ton landslide broke free from the flanks of Mt. La Perouse and flowed nearly 4.6 miles from where it originated. The months May through June offer the most favorable weather for climbing and viewing.

Mount Tom White

Mount Tom White is a prominent 11,191-foot glaciated mountain summit located in the Chugach Mountains, in the U.S. state of Alaska. The remote peak is situated on land managed by Chugach National Forest, 72 mi (116 km) northeast of Cordova, and 20 mi (32 km) north of the Bering Glacier, North America's largest glacier. The mountain lies within the Copper River drainage basin, and is the eighth-highest major peak in the Chugach Mountains. Topographic relief is significant as it ranks 17th in prominence for all peaks in Alaska, and 52nd for all North America peaks. The first ascent of the mountain was made in 1973 by Story Clark, Chris Hall, Tom Kizzia, William Resor, Sarah Robey, and Don White.

Sukakpak Mountain Mountain in the Brooks Range, Alaska, United States

Sukakpak Mountain is a prominent 4,459-foot mountain summit located in the Philip Smith Mountains of the Brooks Range, in the U.S. state of Alaska. The peak is situated 90 miles north of the Arctic Circle near milepost 203 on the Dalton Highway, and 200 mi (322 km) north-northwest of Fairbanks, where the Bettles and Dietrich Rivers merge to form Middle Fork Koyukuk River. The peak's Sukakpak name was reported in 1930 by the USGS as an Inupiat word, said to mean "marten deadfall." From the north, the mountain resembles a carefully balanced log used to trap marten. The name was officially adopted in 1932 by the U.S. Board on Geographic Names.

Dillon Mountain

Dillon Mountain is a prominent 4,820-foot mountain summit located in the Philip Smith Mountains of the Brooks Range, in the U.S. state of Alaska. The peak is situated 93 miles north of the Arctic Circle near milepost 207 on the Dalton Highway, and 200 mi (322 km) north-northwest of Fairbanks, where the Bettles and Dietrich Rivers merge to form Middle Fork Koyukuk River. Sukakpak Mountain rises 3 mi (5 km) to the southwest, and Dietrich Camp of the Trans-Alaska Pipeline lies 3 mi (5 km) to the northwest. The peak was named after John Thomas Dillon (1947-1987), a geologist with the Alaska Division of Geological and Geophysical Surveys who mapped the geology of the southern Brooks Range mineral belt. He died tragically with his father, Stephen Patrick Dillon, in an airplane crash in the Brooks Range while returning home from field work in July 1987. The name was officially adopted in 1990 by the U.S. Board on Geographic Names. This landmark is notable for its massive west face composed of Skajit limestone rising nearly 3,400 feet above the surrounding valley. 

Poss Mountain

Poss Mountain is a prominent 6,180-foot mountain summit located in the Philip Smith Mountains of the Brooks Range, in the U.S. state of Alaska. The peak is situated 80 miles north of the Arctic Circle, five miles east of Dalton Highway, 11.3 mi (18 km) south of Sukakpak Mountain, and 190 mi (306 km) north-northwest of Fairbanks. The peak was named about 1930 by wilderness activist Robert Marshall after "Poss" Postlethwaite, an early and old gold prospector in this area around Wiseman. Robert Marshall described the then 78-year-old Postlethwaite as "the oldest man in the Koyukuk," having spent 32 winters in the area. The name was officially adopted in 1932 by the U.S. Board on Geographic Names. The Poss Mountain Research Natural Area was designated in 1991 to protect natural mineral licks and lambing habitat for Dall sheep. Precipitation runoff from the mountain drains into tributaries of the Middle and South Forks of Koyukuk River.

Mount Chitina

Mount Chitina is an 8,424-foot (2,568-meter) 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 113 mi (182 km) northwest of Yakutat, and 40 mi (64 km) northwest of Mount Logan. Mount Chitina rises 5,000+ ft above the confluence of the Chitina Glacier and the Logan Glacier. Precipitation runoff from the mountain drains into the Chitina River, which in turn is part of the Copper River drainage basin. The first ascent of the peak was made September 24, 1988, by Danny Kost and Donnie Hunton via the west ridge. The mountain's name is derived from the Chitina Glacier located at the base of the north slope, and was first published on a Canadian topographic map in 1958.
