Inyo National Forest lands dominate this high-altitude landscape of Mono County, centered on the volcanic and granitic rises of Cowtrack Mtn and Granite Mtn. The terrain is defined by its water sources, with isolated points like Cowtrack Spring, Indian Spring, and Gaspipe Spring providing critical relief in an otherwise arid environment. Human passage through this portion of the eastern Sierra is traced along historic routes including the Mc Pherson Grade and Baxters Road, which navigate the steep descents into Dexter Canyon and North Canyon. The map reveals a remote geography where high-desert basins like Granite Basin meet timbered slopes, preserved within a network of township and range divisions that have shaped land management in the region for over a century.
