Whitman National Forest dominates this landscape in Union County, where complex ridges and drainages converge near the Ladd Canyon corridor. The topography is defined by significant elevations such as Glass Hill, Tamarack Mtn, and Shaw Mtn, which frame the high-elevation meadows and flats including Howard Meadow, Long Prairie, and Spring Flat. Water features are sparse but critical in this upland environment, represented by the Ladd Canyon Pond and various headwaters like Sheep Creek and the forks of Ladd Creek.
