The dry, dissected plateau of Igo Butte dominates this part of Gilliam County, where high-desert canyons and drainage channels define the rural landscape. Long-standing land use is anchored by the H Johnson Ranch, situated near the intersection of Alville Rd and Ferry Canyon Rd. The presence of the Igo Cemetery suggests an earlier era of community life and settlement that preceded the modern ranching operations. The terrain is deeply carved by watercourses such as Hay Creek and topographical depressions like Tenmile Canyon and Corral Hollow. This survey provides a clear view of the transportation network connecting these remote sites, including the winding paths of Igo Rd and Lamberson Canyon Rd as they navigate the ridges and canyon floors.
