2017 Map of Lefevre Prairie

About this map

The settlement of Lonerock and its associated Lonerock Cem anchor the northwestern portion of this high-country landscape, where the borders of Gilliam, Morrow, and Wheeler Counties meet. The terrain is defined by a series of steep drainages including Pullen Canyon, Crishook Canyon, and Little Dutch Canyon, all feeding into a complex network of creeks such as Juniper Cr and Robinette Cr. To the south and east, the elevation levels into several distinct upland flats including Lefevre Prairie, Lee Prairie, and Camas Prairie, much of which is protected within the Umatilla National Forest. Land use in this area is reflected in the presence of the Brandenbury Reservoir and a system of forest service roads like Nat For Dev Rd 030 and Nat For Dev Rd 070, supporting the remote agricultural and timber economy of the region.
