2021 Map of Petes Valley

About this map

Petes Valley Petes Creek defines the lower drainage of this high-altitude landscape in Lassen County, where intermittent waterways and isolated springs dictate the layout of the land. High elevations are anchored by Horse Lake Mtn and Black Mtn, separated by the deep incision of Long Canyon. The presence of Mapes Spring and Wire Spring highlights the critical importance of water sources in this arid region. Transportation across this portion of the Great Basin is facilitated by remote corridors such as Horselake Rd and Belfast Rd, which connect the scattered topographic landmarks. To the east, the drainage of Snowstorm Cr and the unique formation of The Buttes provide distinct navigational points for those tracing the historical survey lines of the Public Land Survey System.
