2017 Map of Trapper Peak

About this map

Sawtooth National Forest dominates this high-elevation terrain in Cassia County, where the topography is defined by a series of prominent peaks and drainage systems. This 2017 survey details the complex hydrography of the region, including the headwaters of First Fork Rock Cr and Third Fork Rock Cr, which carve through the land between massive features like Harrington Peak and Fuller Peak. The presence of numerous named springs, such as Martindale Spring and Briggs Spring, underscores the critical water resources in this arid upland environment. Navigation through the ridges is limited to established routes like Rock Creek Rd and Oakley-Rogerson Rd, which connect remote points like Telephone Canyon and Freds Mound. The map also identifies specific grazing allotments and landmarks such as Fuller Pasture and Flatiron Mtn, reflecting the area's continued use for livestock and land management.
