1994 Map of Koip Peak

About this map

Mono Pass stands as a significant historical crossing point along the boundary of Tuolumne Co and Mono Co, marking a high-altitude gateway between the high Sierra and the eastern basin. This 1994 revision captures a landscape defined by its mining legacy, where numerous prospects, a Mine Shaft, and various adits are concentrated near Summit Lake. These markings reflect a period of intensive geological exploration and extraction that once characterized the area's economy. The terrain transitions from the eastern slopes of Yosemite National Park into the Ansel Adams Wilderness and Inyo National Forest. High peaks like Koip Peak and Mount Lewis overlook a complex network of alpine water bodies, including the Alger Lakes and the prominent Gem Lake, connected by drainage systems like Rush Creek.
