Malhuer National Forest dominates this high-elevation landscape in Grant County, where the southern portion of the map transitions into the relatively level expanse of Logan Valley. This 2014 survey documents a complex system of drainage and resource management, defined by several significant tributaries such as Summit Cr, Big Cr, and Wickiup Cr which eventually feed the upper reaches of the Malheur River. The terrain is marked by named natural clearings and depressions like Summit Prairie and Corral Basin, which historically served as vital landmarks for grazing and navigation.
