About this map

Umatilla National Forest dominates this landscape along the border of Morrow and Grant counties, where the high-elevation terrain is carved by a complex network of canyons and creeks. At the southern edge of the quadrangle, the North Fork John Day River cuts through the topography, receiving drainage from deep ravines like Coyote Canyon and Board Creek. The map documents a rugged wilderness characterized by prominent landmarks such as Johnny Cake Mtn and Neal Butte, offering a detailed view of the remote water sources vital to this region, including Buckhorn Spring and Tonto Spring.

Tracing the flow of Big Wall Creek and its many tributaries, one can see the intricate natural drainage patterns that define the Blue Mountains area. The presence of features like Mahogany Flat and various named canyons, such as Skookum Canyon and Black Rock Canyon, illustrates the geographic isolation and the primitive road network used for land management and exploration in the late twentieth century.
