1960 Map of Block Mountain

USGS Topo · Published 1975

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.
