About this map

The high plateau of the Modoc National Forest dominates this landscape, characterized by isolated springs and ephemeral water sources. The Pothole Valley cuts through the center of the sheet, surrounded by significant elevations like Bird Spring Ridge to the north and Timbered Ridge to the east. Water management in this arid environment is evident through features such as Boles Tank and the Timbered Ridge Reservoir, which support local livestock or wildlife.

Remote Forest Service routes including Mowitz and Four Mile provide the primary access to the interior. The presence of named water points like Quaking Aspen Spring, Pothole Spring, and Bird Spring highlights the critical importance of specific hydration sites for navigation and land use in this part of California. The geography is further defined by the basin of Clear Lake and the drainage of Boles Cr.
