About this map

Water sources dictate the landscape of this Valley County region, mapped as part of a Missouri River Basin development program. The Cornwell Reservoir serves as a primary landmark in a territory defined by intermittent drainages and essential groundwater access. Numerous named springs, including Vandalia Spring, Burke Spring, and Wire Spring, suggest the critical importance of reliable water for livestock in this rangeland during the late 1960s.

The map reveals a complex network of coulees and creeks, such as Grass Coulee and the West Fork Crooked Creek, that carve through the terrain. Evidence of regional infrastructure appears with a designated Pipeline corridor crossing the southern sections. This survey documents the intersection of natural drainage systems like Buggy Creek and Wolf Creek with the practical needs of Montana ranching, noted by several scattered Corral sites.
