2017 Map of Porcupine Ridge

About this map

Porcupine Mtn and Porcupine Ridge dominate this high-altitude landscape along the border of Utah and Wyoming. The terrain is defined by a dense network of seasonal drainages and creek beds, including Yellow Creek, Willow Cr, and Chicken Cr, which carve through the uplift. In the northern reaches, the Barker Reservoir and the wide drainage of Sage Creek Draw indicate the collection of snowmelt from the surrounding peaks. The map reveals a land utilized for water management and transit, with Yellow Creek Rd and Co Rd 153 following the natural contours of the basin. The southern portion of the quadrangle opens into the Chalk Creek Basin, where the topography softens into alluvial draws like Randall Draw and Section Six Draw, showing how the hydrology of Chalk Cr has historically shaped the local geography.
