2017 Map of Block Mountain

About this map

Sodak Mill sits along the southern bank of the Big Hole River, anchoring a landscape defined by complex water management and high-country relief. This modern topographic survey illustrates the winding course of the river as it forms the boundary between Madison and Beaverhead Counties. Irrigation infrastructure is central to the area's development, evidenced by the Fred Bryant Ditch, Cocanougher Ditch, and Larson-Naranich Ditch which cut across the flats north of the river. The terrain rises sharply to the north and south, featuring landmarks like Block Mtn, Bell Peak, and the distinct ridgeline of the Hogback. The inclusion of a Buffalo Jump near Sandy Hollow points to the deep indigenous history of this valley, while roads like Burma Rd and Hogsback Rd provide access through the numerous gulches and sloughs.
