Fort Rock Valley defines this high desert landscape in Oregon, where a network of section-line roads and remote drainage basins reveal the organized settlement of Lake County. The terrain is characterized by large, ephemeral basins including Schaub Lake, Cream Lake, and Windmill Lake, which are situated across the arid floor of the valley. To the southwest, the Connley Hills rise above the basin floor, providing a stark topographical contrast to the flat northern reaches near the Flatiron. This survey documents a rural environment shaped by the public land survey system, as evidenced by the grid-like alignment of Fort Rock Rd and Thomas Rd, which connect isolated homesteads and ranch lands in this part of the Oregon interior.
