About this map

Lonerock sits at the northern end of this landscape where Lone Rock Cr meets Robinette Cr. The terrain is defined by a series of deep drainage systems and prominent rises, such as Boone Canyon and Oxhead Ridge. Much of the southern territory is protected within the Umatilla National Forest, showing a transition from the lower creek basins to more elevated timberland and ridges.

Local history and genealogy interests are centered on the Lost Valley Cem, located near the intersection of Lost Valley Rd and the E Fork Thirtymile Cr. The map details the administrative divide between Gilliam and Wheeler Counties, as well as the intricate network of water sources like Big Spring and Buckhorn Cr that have long sustained the ranching and agricultural operations in this part of Oregon.
