About this map

Jackass Butte and Black Butte rise above the deeply carved canyon of the Snake River, anchoring a landscape defined by significant historic transit and conservation. The path of the Oregon Trail (South Alternate) cuts across the southwestern terrain, marking the enduring legacy of westward migration through this arid corridor. Most of the river valley is protected within the Snake River Birds of Prey Natural Area, emphasizing the importance of the vertical cliff walls for nesting raptors.

Water management is central to the area's utility, evidenced by the Grand View Irrigation District Canal and several siphons that move water toward agricultural sections like Chattin Flat. The northern reaches include the Idaho National Guard Training and Maneuver Area Area 5, while smaller drainages like McKeeth Wash and Vinson Wash feed into the river system. This survey documents the intersection of historic pioneer routes, modern military use, and critical habitat preservation in the high desert.
