2016 Map of Thirtyone Mile Mountain

About this map

Guffey sits at the northern edge of this high-altitude landscape, where the boundary between Park and Fremont counties divides a terrain of prominent volcanic and metamorphic peaks. The namesake Thirtyone Mile Mountain dominates the central portion of the sheet, surrounded by a complex system of drainage basins including Thirtyone Mile Cr and Currant Cr. These waterways cut deep through the landscape, forming numerous gulches like Louis Gulch and Warmer Gulch. To the south, the peaks of W Antelope Mtn and E Antelope Mtn rise above the Cottonwood Cr drainage, while Wall Mtn and Delilah Peak mark the southern reach of the survey. The mapping reveals a modern network of rural roads and residential lanes such as Taylor Rd and Autumn Creek Dr, reflecting the area's development from a remote mining and ranching district into a region of mountain retreats and land parcels.
