About this map

Silver Lake dominates the eastern horizon of this high-desert landscape in Lake County, bounded by the dramatic descent of Dead Indian Rim. At the turn of the millennium, this revision by the Forest Service highlights a network of water management and recreation within the Fremont National Forest. The geography is defined by seasonal and permanent water sources essential for high-country life, from the Duncan Reservoir to isolated points like Murphy Windmill and Mirror Spring.

Modern recreational use is codified by the Fremont National Recreation Trail, which traverses the southern portion of the quadrangle. The map captures the transitional terrain where the flats surrounding La Brie Lake meet the rising volcanic features of Grassy Butte. Small-scale industrial traces, such as a Gravel Pit, sit alongside natural drainages like Murdock Creek and East Creek, documenting the managed balance of natural resources and public land access in the early 2000s.
