Imperial Valley and the northern reaches of the Dry River channel characterize this high-desert landscape on the border of Crook and Deschutes counties. The terrain is marked by distinctive geological features like Grassy Butte and the broad expanse of Ireland Flat, illustrating a region where water management and infrastructure were paramount. Numerous stock tanks, water wells, and a Substation are scattered across the landscape, connected by an emerging network of improved and unimproved roads.
