2020 Map of Turner Mountain

About this map

Umatilla National Forest encompasses the majority of this landscape in eastern Oregon, where the boundary between Morrow and Grant counties cuts through the northern timberland. The terrain is defined by complex drainage networks and volcanic prominences, with water sources such as Willow Springs and Big Willow Spring providing essential hydrology for the high country. Central to the map is the distinctive Eagle Rock and the namesake Turner Mtn, rising above numerous named canyons like Dark Canyon and Lost Canyon. Evidence of past land management and resource use is found in labels like CCC Spring, while the presence of Sunflower Flat suggests open meadow pockets within the densely forested ridges. This area remains a vital part of the regional watershed, as seen in the confluence of Wilson Creek and Little Wilson Cr flowing toward the lower basins.
