Whitman National Forest land defines this corner of Union County, where high-elevation drainages converge to form the headwaters of major regional waterways. The Grande Ronde River and its upper tributaries, including Limber Jim Creek and the E Fork Grande Ronde River, carve through the landscape, creating a network of ridges and meadows. Key geographic features such as Limber Jim Ridge and the broad opening of Limber Jim Meadow illustrate the characteristic high-country terrain. Small, specialized water resources are evident at Rainbow Reservoirs and the isolated Erickson Lake. The map details an extensive system of forest development roads, such as Nat For Dev Rd 100 and Nat For Dev Rd 51, which provide access to these remote reaches. From the depths of Deadwood Gulch to the seasonal wetlands of Round Meadow, the map captures the complex hydrology and management of this timbered mountain environment.
