The town of Grass Valley serves as the focal point for this section of Sherman County, positioned at the intersection of a grid-like network of country roads and the local drainage system. The landscape is defined by a series of significant erosional features including Grass Valley Canyon, French Canyon, and Macks Canyon, which cut through the high plateau. These canyons dictate the movement of local water through seasonal streams like Draw Cr and Finnegan Cr.
