Mount Eisen

[3] Topographic relief is significant as the south aspect rises 3,500 feet (1,100 meters) above Pinto Lake in one mile.

[5] This mountain was named by the National Park Service, and officially adopted in 1941 by the United States Board on Geographic Names to remember Gustav Eisen (1847–1940), scientist and early conservationist, who played an important role in the establishment of Sequoia National Park.

[1] He was a Sierra Club member for 48 years, and his ashes are interred on the north side of the mountain near Redwood Meadow.

[6] The first ascent of the summit was made July 15, 1949, by Howard Parker, Mildred Jentsch, Ralph Youngberg, and Martha Ann McDuffie.

As fronts approach, they are forced upward by the peaks, causing them to drop their moisture in the form of rain or snowfall onto the range (orographic lift).
