2023 Map of Jim Sage Canyon

About this map

Upper Raft River Valley is defined by a complex network of seasonal and perennial waterways draining from the high terrain of the Jim Sage Mountains. The landscape transitions from the broad, open valley floor to the sharp relief of Jim Sage Canyon and Womack Canyon in the east. Numerous water sources such as Jim Sage Spring, Reed Spring, and Womack Canyon Spring highlight the critical role of water management in this high-desert environment. The Raft River serves as the primary drainage, constricted by a notable geological formation at The Narrows. A grid of local routes like Narrows Rd and Strevell Rd provides access to the remote canyons and creek beds, including Edwards Creek and George Creek, supporting ranching and agricultural activities in this corner of Cassia County.
