2020 Map of Porcupine Ridge
USGS Topo · Published 2020About this map
Porcupine Ridge and Porcupine Mtn define this high-altitude landscape along the border of Utah and Wyoming. The map documents a complex drainage network where Willow Cr and Yellow Cr flow through deeply incised valleys north toward the Uinta County line. The presence of several named draws, such as Randall Draw and Sage Creek Draw, suggests a landscape shaped by seasonal runoff and erosional activity typical of the high mountain west.
