About this map

The Big Hole River carves a central path through this landscape along the border of Madison Co and Beaverhead Co. In 1960, the river's influence on the local economy is evidenced by a complex network of irrigation channels, including the Fred Bryan Ditch, Buhrer-Garrison Ditch, and Cocanougher Ditch, which redirect water across the valley floor. The terrain is defined by dramatic elevations such as the steep Hogback ridge and Block Mountain, with Bell Peak rising in the northwest corner.

Industrial activity centers on the Sodak Mine and its associated Sodak Mill in the southwest, while scattered prospects suggest ongoing mineral exploration. Cultural and historical landmarks are also present, notably the Buffalo Jump near the Burma Road, marking a site of indigenous significance. Numerous gulches like Buhrer Gulch and Ziegler Gulch drain the higher peaks, feeding into the river system near Stevens Slough.
