2022 Map of Seven Lakes Basin

USGS Topo · Published 2022

About this map

The Shasta National Forest encompasses the high-elevation terrain of the Trinity Mountains in this modern survey, where the borders of Siskiyou, Shasta, and Trinity counties converge. The landscape is defined by its glacial hydrology, most notably the Seven Lakes Basin and a cluster of alpine waters including Castle Lake, Lake Helen, and Echo Lake. Long-established routes through this backcountry are documented, with the Pacific Crest National Scenic Trl traversing the ridges above Devils Pocket. This map also records several specific topographic and geological landmarks, such as the prominent Grey Rocks and Asbestos Gulch, reflecting the region's complex mineral and natural history. Significant clearings like Horse Heaven Meadows and summits such as Whalan Summit provide essential reference points for navigating these remote watersheds.
