2024 Map of Rainbow Peak

About this map

Roosevelt Lake and the drainage of Monumental Creek anchor this topographic view of the Salmon River Mountains. The landscape is defined by the convergence of three major protected areas: the Frank Church-River of No Return Wilderness, Payette National Forest, and Boise National Forest. High-elevation landmarks such as Rainbow Peak, Dewey Hill, and Thunder Mtn rise above a complex network of waterways, including Annie Creek and Threemile Creek. The presence of the Monumental Creek Trl and the Nat For Dev Rd 375 suggests a primitive transportation corridor through these steep drainages. Topographical details illustrate the varied terrain from Gold Ridge down to the confluence of the South Fork Trap Creek, providing a clear record of the watershed and ridges that historically dictated access to this central Idaho backcountry.
