Canyon Ferry Lake dominates the southern half of this landscape, where the Missouri River is impounded by the Canyon Ferry Dam. This area reveals a complex history of water management and recreation, featuring the Powerplant, Pumping Sta, and the Yacht Basin along the shoreline. Evidence of the region’s earlier industrial life is found to the north in the Helena National Forest, where the Golden Messenger Mine, Little Dandy Mine, and several unnamed Prospects line the steep drainage of Trout Creek. The settlement of York serves as a small hub for these northern gulches. Notable for local history, the map identifies Cemetery Island Recreation Area and Cemetery Hill, alongside numerous named gulches like Rattlesnake Gulch and Hellgate Gulch that define the mountainous terrain.
