1996 Map of Sevenmile Creek

USGS Topo · Published 1998

About this map

The Umatilla Indian Reservation Boundary defines the northern reaches of this landscape, where the high-elevation terrain of the Blue Mountains transitions into complex drainage systems. A network of unimproved roads and 4WD tracks navigates a series of steep canyons, including McDonald Canyon and Axle Canyon, which channel seasonal water into the broader basins below. This 1996 survey reflects a working landscape characterized by resource management and land allotment, evident in the presence of a Gravel Pit and the systematic naming of features like Rankin Flats and Porter Hill. The hydrologic pattern is dominated by Sevenmile Creek and Little McKay Creek, supported by scattered water sources such as Sevenmile Spring and Spring points. The topographic relief of Rocky Ridge provides a natural divide for the watersheds of East Birch Creek and Pearson Creek in the south.
