2023 Map of Big Horse Basin Gap

About this map

Horse Basin and the adjacent Big Horse Basin Gap characterize this high-elevation corner of Owyhee County. The landscape is defined by the sharp incisions of Big Jacks Creek and Little Jacks Creek, both of which are protected within the extensive Big Jacks Creek Wilderness and Little Jacks Creek Wilderness. These deep drainage systems create a dramatic relief pattern against the surrounding plateaus, where the seasonal flow of Rattlesnake Creek joins the larger network of wild and scenic waters.
