2023 Map of Sevenmile Creek

About this map

Sevenmile Creek and the southern canyons of Umatilla County define this area of the Blue Mountain foothills. The landscape is marked by a series of steep drainages including McDonald Canyon, Gibson Gulch, and Jimene Canyon, which descend toward the northern plateau. Evidence of long-standing ranching and rural navigation is found in the network of county roads like Little McKay Creek Rd and Pearson Creek Rd, which follow the natural contours of the creeks. Higher elevations feature Rocky Ridge and Porter Hill, providing clear vantage points over the agricultural pockets at Rankin Flats and Wood Hollow. The southern edge of the map is anchored by the corridor of East Birch Creek, a vital water source for the surrounding land. This contemporary survey details the complex system of gulches and ridges that continue to shape local movement and land use in this part of Oregon.
