The Missouri River carves a central path through this Broadwater County landscape, defining a valley dominated by a complex network of 21st-century irrigation infrastructure. The small community of Toston sits at a critical junction where the river meets the Broadwater - Missouri Canal and the Big Springs Ditch, reflecting the long-standing importance of water management in this part of Montana. From Holker in the north to Brewer in the south, the terrain transitions from the fertile river bottoms near Devils Bottom to the rising elevations of Dry Hollow and the foothills to the east.
