1979 Map of Disaster Peak

About this map

Pacific Crest National Scenic Trail traverses the high-altitude divide of the Sierra Nevada, marking the boundary between the Toiyabe National Forest and the Stanislaus National Forest. The landscape is defined by its dramatic relief, including the namesake Disaster Peak and the prominent The Iceberg, overlooking the Iceberg Meadow in the southwest corner. The drainage patterns on this sheet are particularly distinct, with the East Fork Carson River flowing north through Golden Canyon and Murray Canyon, while the Clark Fork drains the southern slopes toward the Alpine and Tuolumne County line. These watersheds are punctuated by remote high-country basins such as Poison Lake, Tamarack Lake, and Boulder Lake. Evidence of early backcountry recreation and land management is clear, with the Boulder Lake Trail and numerous unnamed pack trails providing the only access to the interior peaks like Stanislaus Peak and Whitecliff Peak.
