2017 Map of Ratio Mountain

About this map

Deerlodge National Forest dominates this section of Jefferson County, where the high mountain terrain of the Boulder Batholith landscape is deeply incised by drainages like State Cr and Little Whitetail Cr. The map highlights a remote wilderness defined by prominent peaks including Ratio Mtn and Goodwin Mtn, which overlook high-elevation open spaces such as Lower Whitetail Park and the ominous Poison Flats. The influence of early 20th-century resource extraction and backcountry access is evident through the inclusion of State Mine Rd and the network of forest routes that navigate through Whitetail Valley. Critical water sources for both wildlife and travelers in this arid mountain environment are meticulously marked, ranging from the man-made Keogh Reservoir to natural seeps like Wildhorse Spring and Roadside Spring, providing essential waypoints for anyone navigating the deep canyons and timbered slopes of the Elkhorn Mountains.
