Big Lost River drainage patterns and high mountain terrain define this portion of Custer County as it appeared in the early 21st century. The landscape is marked by significant topographical landmarks such as Lehman Butte and the extensive Lehman Basin, while the valley floor is shaped by a network of waterways including Warm Springs Creek and Hamilton Creek. A key point of interest for local history is the Mackay Fish Hatchery, situated near Barton Cemetery at the base of the foothills. The presence of routes like Burma Rd and Old Chilly Rd illustrates the rural infrastructure connecting disparate grazing and water resources such as Horse Wallow and Wood Road Spring. This survey captures the transition from the irrigated valley bottoms to the high passes at Corral Creek Summit.
