About this map

The Big Hole River carves through this Montana landscape, marking the boundary between Madison Co and Beaverhead Co. Along the northern banks, historical agricultural infrastructure is evident in the intricate network of irrigation channels, including the Fred Bryan Ditch, Buhrer-Garrison Ditch, and Cocanougher Ditch. These systems suggest a period of intensive ranching and water management in the valley below the prominent Hogback ridge.

Inland from the river, the map reveals industrial and prehistoric footprints. The presence of the Sodak Mine and the nearby Sodak Mill indicates mid-century mineral exploration, while the label for a Buffalo Jump near Sandy Hollow points to the much older cultural history of the land. High points like Bell Peak and Block Mountain overlook a terrain punctuated by numerous seasonal water sources such as Garrison Spring and Chokecherry Spring.
