Oregon Trail (Approx Route) segments cut across the northern reaches of this high desert terrain, marking the historic path of westward migration through Gilliam County. The landscape is defined by deep drainages including Eightmile Canyon, Fourmile Canyon, and Cow Canyon, which carve through the plateau surrounding Hickland Butte. Evidence of agricultural infrastructure is sparse but present, noted by scattered Well sites and isolated Storage Bins used by local ranchers. Genealogists may find interest in the distinct Cem markings located on the plateau, providing specific coordinates for small burial sites tucked away in the draws. The map also delineates the jurisdictional boundary between Gilliam Co and Morrow Co near the southern Base Line, reflecting the formal organization of these eastern Oregon ranchlands in the mid-1960s.
