1960 Map of Block Mountain

USGS Topo · Published 1986

About this map

The Big Hole River winds through this 1960 landscape, serving as a natural boundary between Madison and Beaverhead Counties. The terrain is characterized by dramatic elevation changes, from the prominent Bell Peak and Block Mountain to the narrow valley floor where early ranching and irrigation infrastructure is evident. Water management is a primary theme of the area, shown through the extensive network of the Cocanougher Ditch, Fred Bryan Ditch, and several natural water sources like Garrison Spring and Chokecherry Spring.
