2023 Map of Blitzen SW

About this map

Catlow Valley dominates this high-desert landscape in Harney County, illustrating a vast and sparsely populated basin in southeastern Oregon. This 2023 survey by the U.S. Geological Survey and BLM details the intermittent drainage patterns typical of the Great Basin, where seasonal watercourses like Guano Slough define the terrain's hydrology. The presence of the W Guan route suggests the critical importance of established access roads for ranching and public land management in this isolated region. The map provides a clear look at the Public Land Survey System (PLSS) grid, showing the boundaries of several townships including t35s r30e, which organizes the management of these sprawling rangelands and protected wildlife areas.
