Telocaset sits at a geographic transition where the high desert meets the forested uplands of Eastern Oregon. This 2017 survey by the U.S. Geological Survey details a landscape defined by water management and high-country grazing, centered on the Thief Valley Reservoir which dams the Powder River along the Union Co Baker Co line. The terrain rises sharply to the northeast into the Whitman National Forest toward Clark Mtn, while to the west, the topography is carved by names like Pyles Canyon and Government Gulch. Local water sources such as Lynch Spring, Foley Spring, and Glass Spring dot the hillsides, indicating the essential role of hydrology in this dry environment. The presence of Telocaset Hill and Riverdale Hill overlooks a network of rural roads including Thief Valley Rd and Railroad Dr, tracing the path of transit through the valley floor.
