Umatilla National Forest encompasses the vast majority of this Morrow County landscape, defined by a complex network of canyons and high plateaus. The topography is dominated by large, named openings such as Big Rock Flat and Snowshoe Flat, which alternate with prominent elevations like Opal Butte and Barlow Butte. This area serves as a significant drainage basin, with Rock Creek and its many tributaries, including Tupper Creek and Keeney Creek, carving deep paths through the forest.
