About this map

Rattlesnake Hills and the prominent Beaver Rim define this high-altitude landscape in central Wyoming, where historical settlement is marked by isolated sites like the Holiday Homestead (Aband) and the Aspell Homestead Site. The terrain is a network of drainage systems including Deer Creek, Little Cross Creek, and the headwaters of the Middle Fork Sage Creek, which flows south from Black Mountain.

Transport through this part of the Ervay Basin relies on a mix of old and modern infrastructure, from the Waltman Sweetwater Road and a high-clearance Freight Road to a remote Landing Strip. The presence of the Boyle Reservoir and a cross-country Pipeline highlights the region's management of water and energy resources within a landscape of significant geological relief, such as the French Rocks formation.
