The Denali Fault is caused by stresses created by the low-angle subduction of the Yakutat microplate underneath Alaska. The Denali Fault Bend is characterized as a gentle restraining bend. [16] The Denali Fault Bend represents a curvature in the Denali Fault that is approximately 75 km long. This curvature creates what is known as a "space ...
Two notable events in the mountain's history include a large rhyolite flow which traveled some 11 miles (18 km) to the north east of the peak and has a volume of about 5 cubic miles (21 km 3), and another flow which erupted from a rift zone on the flank of the volcano some 320,000 years ago. The second flow was basaltic in nature and marks the ...

The Denali Fault is a major intracontinental dextral (right lateral) strike-slip fault in western North America, extending from northwestern British Columbia, Canada to the central region of the U.S. state of Alaska.
Tectonic history Denali from Ruth Glacier. Denali National Park and Preserve is located in the central area of the Alaska Range, a mountain chain extending 600 miles (970 km) across Alaska. Its best-known geologic feature is Denali, formerly known as Mount McKinley. Its elevation of 20,310 ft (6,190.5 m) makes it the highest mountain in North ...
Mount Spurr is a stratovolcano located at the northeastern end of the Aleutian Volcanic Arc which has two vents, the summit and nearby Crater Peak. Parts of the Alaska Range are protected within Wrangell-St. Elias National Park and Preserve, Denali National Park and Preserve, and Lake Clark National Park and Preserve.
Mount Foraker is a 17,400-foot (5,304 m) mountain in the central Alaska Range, in Denali National Park, 14 mi (23 km) southwest of Denali.It is the second highest peak in the Alaska Range, and the third highest peak in the United States.
The 1967 Mount McKinley disaster occurred in July 1967 when seven climbers died on Denali (then still officially known as Mount McKinley) while attempting to descend from the summit in a severe blizzard estimated to be the worst to occur on the mountain in 100 years. [1]
Iliamna Volcano, or Mount Iliamna (Dena'ina: Ch’naqaĊ’in; Sugpiaq: Puyulek), is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve , the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of ...
