Whitman National Forest dominates this landscape in Union County, where the high ridges of Grey Mountain and the prominent Gasset Bluff overlook the eastern edge of the Grande Ronde Valley. The drainage patterns here are well-defined by Indian Creek and the various forks of Clark Creek, which cut through the timbered slopes before descending toward the Grande Ronde River at the valley floor.
