About this map

The Umatilla National Forest landscape across the Morrow Co Grant Co boundary is defined by a dense network of springs and canyons. High points like Turner Mountain and China Cap overlook a terrain carved by Big Wall Creek and its numerous tributaries. The distribution of named water sources, such as Big Willow Spring and Kingbolt Spring, indicates the vital importance of water management in this high-elevation forest environment during the late twentieth century.

Evidence of historical land use and infrastructure appears in the naming of Happy Jack Ridge and the CCC Spring, the latter referencing the Civilian Conservation Corps legacy in the region. Transportation and resource extraction are marked by features like the Gravel Pit near Wilson Prairie and various stock ponds. The map captures a moment when the natural drainage systems of Cat Canyon and Dark Canyon remained central to the geography of these southern Blue Mountain foothills.
