2020 Map of The Arch

About this map

Jarbidge River carves a deep, winding path through the high desert of Owyhee County, creating a dramatic landscape of steep canyons and flat-topped tables. This 2020 survey illustrates the isolation of the region, where the river's course is flanked by Arch Canyon and the prominent landmark of The Arch. The terrain transitions from the open expanse of Inside Desert in the northeast to the Diamond A Desert in the west, with geological features like Crater Hole and Arch Table marking the rimlands. Seasonal water sources such as Cougar Cr and Cougar Spring are critical points in this arid environment, which remains largely defined by its natural topography rather than human settlement.
