Porcupine Hills dominate the southern landscape of this Sioux County region, surveyed in the early 1970s. The geography is defined by the drainage of Porcupine Creek and the man-made impoundment at Froelich Dam, which includes the Froelich Dam State Management Area. This site reflects mid-century water management efforts by the State Water Commission to support the Missouri River Basin development. A stretch of the C M St P & P railroad cuts through the southwest corner, providing a vital transportation link for this rural landscape. Scattered features such as a Well and a Riser suggest the agricultural and industrial infrastructure required to manage resources in this high-plains environment within the Standing Rock Indian Reservation.
