About this map

Thumb Tank Peak and the surrounding high country of Sierra County define this landscape of interconnected drainages and prominent volcanic summits. The terrain is marked by a network of ranching infrastructure, where vital water sources like Sophie Spring, Aragon Spring, and Thumb Tank sustained operations across the high plateaus. Strategic overlooks such as Grandview Mesa and Yellow Mountain rise above deep-cut passages including Buck Canyon and Madera Canyon.

The hydrography of the region is centered on the forks of Palomas Creek, which transition from the steep relief of Kelly Canyon and Deadman Canyon toward the broader alluvial flats. This 2023 survey illustrates the continued importance of livestock water management in the arid southwest, evidenced by numerous named catchments like Lard Tank, Chris Tank, and Polo Tank that remain key landmarks in a territory otherwise defined by its challenging verticality.
