About this map

The East Fork Sevier River carves a winding path through this corner of the Sevier Plateau, defining a landscape of deep canyons and high meadows along the Piute Co and Garfield Co line. The terrain transitions from the heights of Forshea Mtn and Phonolite Hill down to the eastern valley floor, where the East Fork Canal and Otter Creek Reservoir support local agriculture near the settlement of Antimony.

Water sources are a primary feature of this arid high-country environment, with numerous named points such as Hodge Ranch Spring, Dripping Spring, and Blind Spring scattered across the slopes of the Fishlake National Forest. The map also captures the local transportation network, from the corridor of Old Hwy 62 to the remote Forshea Mountain Trl, illustrating how human movement follows the natural breaks of Kingston Canyon and Log Hollow.
