Sunflower Hot Springs sits along the Middle Fork Salmon River, highlighting the geothermal and hydrologic character of this mountain landscape. The area is defined by the meeting of the Boise National Forest and Challis National Forest, where steep drainages like Jackass Gulch and Slide Cr descend from the namesake Sliderock Ridge. Human activity is concentrated along the river corridor and its tributaries, evidenced by the Mahoney Creek USFS Airport and local landmarks such as Cougar Creek Ranch. Remote camping facilities, including Upper Jackass Flat Campground and Hood Ranch Campground, provide access to the various forks of Little Loon Cr and N Fork Sheep Cr, documenting the modern recreational footprint within these expansive national forest boundaries.
