Colosseum Mountain is a 12,473-foot-elevation (3,802 meter) double summit mountain located on the crest of the Sierra Nevada mountain range in northern California. [5] It is situated on the common border of Fresno County with Inyo County, as well as the shared boundary of John Muir Wilderness and Kings Canyon National Park. It is 12 miles (19 km) northwest of the community of Independence, 1.2 miles (1.9 km) east of Mount Cedric Wright, 2.6 miles (4.2 km) west of Sawmill Point, and 1.6 miles (2.6 km) south-southeast of Mount Perkins, the nearest higher neighbor. The lower east summit is 12,451-feet in elevation and marked as Colosseum Mountain on maps, but the 12,473-foot west summit is higher. [2] Approximately 1,000 feet distance separate the two summits. The John Muir Trail passes to the west of this peak, providing an approach to the mountain. The first ascent of the summit was made August 5, 1922, by Chester Versteeg, a prominent Sierra Club member, via the southwest face. [7] [8]

Climate

According to the Köppen climate classification system, Colosseum Mountain has an alpine climate. [9] Most weather fronts originate in the Pacific Ocean, and travel east toward the Sierra Nevada mountains. 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). Precipitation runoff from this mountain drains west into Woods Creek, which is a tributary of the South Fork Kings River, and east to the Owens Valley via Division Creek.

Striped Mountain

Striped Mountain is a 13,179-foot-elevation mountain summit located on the crest of the Sierra Nevada mountain range in northern California.

Climbing routes to this mountain include Taboose Pass and the West Ridge. The John Muir Trail passes west of this peak, providing an additional approach to the mountain. Bolton Coit Brown gave this mountain its descriptive name in 1895 when he later wrote: "That nearest the pass is strikingly barred across its steep craggy summit with light streaks. As this is an unusually marked case of this peculiarity and as it seems well occasionally to have a mountain whose name bears some relation to its visible character, I called it Striped Mountain." The numerous stripes are lightly-colored granitic dikes of Lamarck granodiorite intruded within Striped pluton, which is composed of fine-grained mafic granodiorite.
