About this map

Petes Valley and its high-desert topography define this corner of Lassen County, where intermittent drainage and volcanic landforms shape the landscape. Named peaks like Black Mtn, Horse Lake Mtn, and Tunnison Mtn create a rim around the central basins, which are fed by seasonal flows from Petes Cr and Snowstorm Cr. Essential water sources for the cattle and wildlife in this arid region are marked by Wire Spring and Mapes Spring.

Transportation through this high-altitude terrain is limited to historic routes such as Horselake Rd, Woodranch Rd, and Karlo Rd, which follow the contours of the land. The presence of The Buttes and Long Canyon highlights the geological complexity of this section of Northeastern California. This survey records the land before recent shifts in management, preserving the network of county and ranch roads used to navigate the open range.
