About this map

Fremont National Forest defines the western expanse of this high-desert landscape in Lake County, where scattered springs and man-made water catchments support life across the basin. The terrain is punctuated by volcanic features like Oat Butte and Wing Butte, while lower elevations are marked by the extensive Oatman Flat and the curious geological formation known as the Devils Ball Diamond.

Water management is central to this environment, evidenced by named features such as Schumacher Reservoir Number Five and Logger Waterhole. To the southeast, the geography shifts toward marshland and seasonal basins, including Pauline Marsh and the clustered waters of Lily Lake and Ward Lake. This 2017 survey reflects a modern inventory of the region's ranching and forestry infrastructure, capturing the network of unpaved access points like Bear Flat Rd and Oatman Flat Ln that connect these remote water sources.
