Mount Grosvenor is an 8,400-foot (about 2,560 meters) peak in the Alaska Range, located in Denali National Park and Preserve, Alaska, United States. It sits on the west side of Ruth Gorge, just north of Mount Church and just south of Mount Johnson. The nearest higher peak is Mount Wake, about 1.3 miles to the northwest. Its east face features a dramatic 4,000-plus-foot vertical granite wall.

Naming and first ascent: The mountain was named by explorer Dr. Frederick Cook, who claimed to have climbed Denali in 1906—a claim later disproved. The peak’s unofficial name honors Gilbert Hovey Grosvenor, longtime head of the National Geographic Society and a pioneer of photojournalism. The first ascent was in 1979 by Gary Bocarde, Charlie Head, John Lee, and Jon Thomas.

Climate and best time to visit: Mount Grosvenor lies in a subarctic climate with long, cold winters and cool summers. Winter temperatures can drop below −20°C, with wind chills under −30°C. The best months for climbing or viewing are May and June.

Geology: The mountain is part of the Alaska Range and is composed of granite.
