2017 Map of Big Rock Flat

About this map

Umatilla National Forest dominates this section of the Blue Mountains, where the landscape is defined by a dense network of forest development roads and specialized water features. The terrain transitions from high buttes like Barlow Butte and Opal Butte to broad upland plateaus, including Big Rock Flat and Snowshoe Flat. This 2017 survey shows how the land is managed for both preservation and utility, evidenced by the Rough Canyon Reservoir and numerous named water sources such as Government Spring and Opal Spring that support the local ecosystem. Notable geographic features like Beaver Slide Ridge and the distinctively named Morphine Ridge suggest a history of local nomenclature tied to the timber or ranching eras. The map's layout of roads, such as Kinzua Rd and Tupper Rd, reveals the primary corridors through this remote portion of Morrow and Wheeler Counties.
