About this map

Pinnacle Rocks and the distinctive Miller Buttes dominate this landscape on the border of Converse and Niobrara counties. The 1981 terrain is defined by a complex network of seasonal drainages, including Nachtman Draw, Sawmill Draw, and Archie Draw, which feed into larger watercourses like Cow Creek and Middle Creek. This area illustrates a typical Western ranching and resource landscape, where topographic features carry the names of early settlers or local landmarks like the Rattlesnake Hills.

Water management is central to the area's utility, anchored by the Middle Creek Reservoir and its associated Spillway. Transportation and infrastructure are sparse, consisting primarily of the Cow Creek Road and an industrial Pipeline cutting through the northeast corner. Several drill holes scattered across the quadrangle suggest geological exploration in the late 20th century, even as the primary land use remains centered on the creek-fed valleys.
