2021 Map of Crystal Crag

About this map

Devils Postpile National Monument and the surrounding high-country wilderness of the Sierra National Forest are documented in this modern survey. The map details a complex geological and recreational landscape where the Middle Fork San Joaquin River passes through a corridor of hydrothermal features, including Reds Meadow Hot Springs and the more remote Iva Bell Hot Springs. To the east, the volcanic and glacial history of the Mammoth Lakes area is evident in landmarks like Dragon's Back, Crystal Crag, and the Bottomless Pit. A dense network of trails, including the Pacific Crest National Scenic Trl, connects high-altitude meadows such as Summit Meadow and Fox Meadow with the lake basins of Lake George and Lake Mary. This document records the intersection of three counties—Mono, Madera, and Fresno—across the Silver Divide.
