Mount Grosvenor (Alaska Range)

Mount Grosvenor is an 8,400+ ft (2,560+ m) mountain summit located in the Alaska Range, in Denali National Park and Preserve, in Alaska, United States. It is situated on the west side of the Ruth Gorge, 0.87 mi (1 km) northwest of Mount Church and 0.54 mi (1 km) south of Mt. Johnson. Its nearest higher peak is Mount Wake, 1.32 miles (2.12 km) to the northwest. Despite its relatively low elevation, it is notable for its east face with over 4,000 feet of vertical sheer granite. The mountain was named by famed explorer Dr. Frederick Cook who claimed the first ascent of Mount McKinley in 1906, but was later disproved.[2][3] This peak's unofficial name honors Gilbert Hovey Grosvenor (1875–1966), President of the National Geographic Society, father of photojournalism, and the first full-time editor of National Geographic magazine. The first ascent of the peak was made in 1979 by Gary Bocarde, Charlie Head, John Lee, and Jon Thomas.[4]
