The Stansbury Mountains are mostly a massif, with a continuous ridgeline from north to south, and they are connected at their south with the similarly aligned Onaqui Mountains. The range is widest at the south, about 10 miles, and narrows to about 6 miles at the Great Salt Lake. Its northernmost 3 miles narrow at Timpie to Long Rock Basin. At the lakeshore, bordering Timpie and the mountains' foothills, lies Timpie Springs Waterfowl Management Area.
