Tokosha Mountains is a 6,148 ft (1,870 m) multi-peak massif located in the Alaska Range, in Denali National Park and Preserve, in Alaska, United States. It is situated between the toes of Ruth Glacier and Tokositna Glacier, 27 mi (43 km) south-southeast of Denali and 26 mi (42 km) northwest of Talkeetna.[3] Despite its relatively low elevation, it is notable for its Teton-esque granite spires which can be seen from the George Parks Highway. Precipitation runoff from the mountain drains into the Tokositna River → Chulitna RiverSusitna River. Topographic relief is significant as the highest summit, Grand Tokosha, rises 3,850 feet (1,173 meters) above the Ruth Glacier in one mile (1.6 km).

History

[edit]

In the Denaʼina language, tokosha means "treeless" or "treeless area". The mountain was named in 1906 by explorer Belmore Browne of the Cook Expedition which attempted to climb Denali. This landform's toponym was officially adopted in 1962 by the U.S. Board on Geographic Names.[3] The first ascent of Grand Tokosha was made on March 3, 1975, by David Johnston and Brian Okonek.[4]
