Umatilla National Forest encompasses the majority of this high-elevation landscape, where the terrain transitions from the steep, drainage-cut slopes of Zion Slope to the broad, level expanses of Thompson Flat and Buckaroo Flat. The map reveals a complex network of forest access routes, including the E W Trl and various numbered roads like 5320 Road Trl, which navigate the deep canyons carved by Potamus Creek and Thompson Creek.
