Pinto Ridge dominates the northern landscape of this Columbia Basin quadrangle, where the border of Douglas and Grant counties follows a straight east-west line across the high plateau. The drainage network is defined by deep incisions like Rattlesnake Cr and McCartney Cr, which feed into the larger Douglas Cr system. This arid environment is marked by numerous vital water sources, including Rattlesnake Springs, Mineral Spring, and Bowers Spring, which historically dictated movement and land use in this part of Washington.
