2020 Map of Marsh Peak

About this map

Marsh Peak dominates this high-elevation portion of the Ashley National Forest, serving as a central drainage point for the surrounding glacial basins. The landscape is defined by its extensive water network, including Lakeshore Basin, the Hopper Lakes, and Fish Lake. To the south, human engineering and access are evident through the Dry Fork Flume and the Dry Fork Canyon Rd, which follow the natural contours of the terrain toward lower elevations. The map reveals a high-country economy and recreation system where mountain peaks like Mosby Mtn and deep depressions like Brownie Canyon are linked by primitive routes such as the Ashley Driveway and the more established Red Cloud Loop. Several large meadows or "parks," such as Corral Park and Big Park, suggest historical grazing or camping use within these alpine reaches.
