2020 Map of Andies Prairie

About this map

Umatilla National Forest dominates this landscape in the Blue Mountains, where a complex network of ridges and canyons defines the drainage patterns between Umatilla and Union counties. The terrain is marked by high elevations like Buck Mtn and Huckleberry Mtn, separated by deep cuts such as Glenn Canyon and Steele Mill Canyon. Water sources are abundant, with numerous family-named and geographic springs including English Spring, Patusway Spring, and Will Rogers Spring feeding into the N Fork Umatilla River and Phillips Cr. The map reveals a specialized recreation and transit network designed for seasonal use, featuring the Umatilla Rim Trail and several winter-specific routes like the Ridge Rim Loop (Snow) and Viewpoint Cutoff (Snow). Open meadows such as Horseshoe Prairie and Andies Prairie provide distinct breaks in the forested topography of t3n r38e.
