Pine Ridge dominates the southwest portion of this high-desert landscape, where the elevation rises significantly above the surrounding plains. This modern topographical study captures the arid character of central Oregon, defined by ephemeral water systems and infrastructure designed for water management in a rain-shadow climate. The northern edge of the map features the Houston Reservoir Number Two and Houston Reservoir Number Three, critical infrastructure along the Crook Co Deschutes Co line. The course of the Dry River cuts through the northeast, illustrating the natural drainage patterns of this volcanic region. Cultural development is sparse, primarily represented by a geometric grid of public land divisions and the thoroughfare of Merrill Rd, which provides access through the high plateau country.
