Lefevre Prairie and the surrounding high-plateau landscape of the Umatilla National Forest define this region at the intersection of Gilliam, Morrow, and Wheeler Counties. This mid-1990s data reflects a landscape shaped by intermittent water sources and the varied topography of the Blue Mountains, where Lonerock Cemetery serves as a lone marker of earlier community ties. The terrain is deeply incised by drainages such as Buttermilk Canyon and Stahl Canyon, while livestock management is evident through the presence of Brandenburg Reservoir and numerous scattered springs. High-altitude meadows like Scot Prairie and Pool Prairie are mapped alongside distinctive landmarks such as The Frog, illustrating the traditional nomenclature used by local ranchers and foresters. The survey also precisely details the First Standard Parallel South, a critical baseline for regional land division.
