The high-elevation landscape of Challis National Forest dominates this Idaho survey, characterized by the prominent rise of Mahogany Hill and the deep incisions of Mulkey Gulch and Dry Canyon. This terrain gives way to the relatively level Pahsimeroi Valley, where the Pahsimeroi River meanders north across the Custer and Lemhi county line.
