About this map

Washburn Basin defines the high-desert landscape where the border of Malheur County, Oregon, meets Humboldt County, Nevada. This high-altitude drainage network is characterized by seasonal water sources and expansive volcanic terrain. Essential water points for local land use are marked at Old Corral Spring, Rock Spring, and Mud Spring, highlighting the critical importance of reliable hydration in this arid environment.

The map reveals a complex system of seasonal creeks, including Washburn Creek, Little Washburn Creek, and Riser Creek, which flow through features like Basco Canyon. These drainages are separated by prominent elevations such as Black Mountain and Long Ridge. The lack of road infrastructure and human settlements on this 2015 survey emphasizes the area's primary role as open range and wilderness, where topographic features like Bull Basin serve as primary landmarks for navigation.
