Pyramid Peak is a 2,136-foot-elevation (651-meter) summit in Alaska, United States.

Description

Pyramid Peak is part of the Aleutian Range. [5] This iconic landmark of the Dutch Harbor area is set two miles (3.2 km) south of Unalaska on Unalaska Island of the Aleutian Islands. Precipitation runoff from the mountain drains into Captains Bay and Iliuliuk Bay. Topographic relief is significant as the summit rises over 2,100 feet (640 meters) above tidewater of Captains Bay in approximately one mile (1.6 km). The mountain's descriptive toponym was published in 1875 by the United States Coast Survey and has been officially adopted by the United States Board on Geographic Names. [4]

Mount Foresta is an 11,000+ ft multi-peak massif located in Wrangell–St. Elias National Park, in the Saint Elias Mountains of Alaska in the United States. Rising high above the lower western margin of the Hubbard Glacier, the summit of Mount Foresta is just over nine miles (14 km) from tidewater at Disenchantment Bay, 12 mi (19 km) northwest of Mount Seattle, 14.5 mi (23 km) southeast of Mount Vancouver, and 46 mi (74 km) north of Yakutat.

<span class="mw-page-title-main">Mount Abbe</span> Mountain in Alaska, United States

Mount Abbe is an 8200+ feet double summit mountain located in the Fairweather Range of the Saint Elias Mountains, in southeast Alaska. The peak is situated near the terminus of the Johns Hopkins Glacier, within Glacier Bay National Park and Preserve, 100 mi (161 km) northwest of Juneau, and 8.2 mi (13 km) northeast of Mount Orville. Although modest in elevation, relief is significant since the mountain rises up from tidewater in less than two miles. Mount Abbe is often seen and photographed with the Johns Hopkins Glacier, which is a popular destination for cruise ships. The mountain was named in 1936 by William Osgood Field and William Skinner Cooper, of the American Geographical Society, for Cleveland Abbe Jr., (1872-1934), an American geographer. Abbe received a Ph.D. in 1898 from Johns Hopkins University. The Gilman Glacier and Clark Glacier on the mountain's slopes were named for Daniel Coit Gilman, the institution's first president, and William Bullock Clark who was a professor of geology at the university. The mountain's name was officially adopted in 1937 by the United States Geological Survey. The first ascent of the south summit was made June 11, 1977, by Jim Wickwire and Dusan Jagersky via the Southeast Face. Three days later, Dusan Jagersky was killed while descending an unnamed peak. The first ascent of the north summit was made July 14, 1991, by Walter Gove and William Pilling. The months May through June offer the most favorable weather for climbing Mount Abbe, but it's a challenging climb in any conditions, with few attempts.

<span class="mw-page-title-main">Mount Cooper (Alaska)</span> Mountain in Alaska

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.

Mount Wordie is a 4,700+ foot mountain summit located in Glacier Bay National Park and Preserve, in the Alsek Ranges of the Saint Elias Mountains, in southeast Alaska. The mountain is situated 80 mi (129 km) northwest of Juneau, 4 mi (6 km) south of Carroll Glacier, and 3.1 mi (5 km) north of Mount Merriam which is the nearest higher peak. Although modest in elevation, relief is significant as the mountain rises up from tidewater in less than two miles. Precipitation runoff from the mountain drains into Glacier Bay Basin. Weather permitting, Mount Wordie can be seen from Queen Inlet and Wachusett Inlet of Glacier Bay, which is a popular destination for cruise ships.
