About this map

Gibbon sits at the convergence of mountain ridges and the winding Umatilla River, marking a point where tribal lands and federal forests meet. This 1990s revision by the U.S. Forest Service traces the complex geography of the Umatilla Indian Reservation Boundary as it cuts across the northern slopes of Wildhorse Mountain. The landscape is defined by its dramatic relief, with evocative names like Starve-to-Death Ridge and Plenty Bear Ridge hinting at the traditional knowledge and history of the Blue Mountains region.

Transportation through this difficult terrain is represented by the Boston Line, which navigates the steep grades of Rattlesnake Ridge. Smaller settlements like Bonifer and water sources such as Rock Spring provide specific points of interest for genealogists tracing family ties to the Umatilla National Forest. The map detail captures the numerous drainages feeding into the river, including Meacham Creek and Hagen Creek.
