1962 Map of Rattlesnake Mountain

USGS Topo · Published 1979

About this map

Rattlesnake Mountain and Baldy Mountain define this stretch of the Montana landscape, captured during the early 1960s with updates through the late 1970s. The map illustrates a transitional period for regional land use, where established homesteads like the Old Synnes Ranch and Old Thorne Ranch sit alongside developing infrastructure. The inclusion of the Gates of the Mountains Interchange in purple revision markings highlights the growing connectivity of this high-elevation terrain with broader transportation networks. Below the peaks, the drainage patterns of McLeod Basin and Hilger Valley reveal a complex network of seasonal flows and gulches. Evidence of resource exploration appears at a Prospect site near Trust-to-Luck Gulch, providing a specific data point for those researching historical mining activity or local ranching genealogy in the vicinity of McLeod Gulch.
