Deerlodge National Forest dominates this section of Jefferson County, where the high-altitude landscape is defined by the summits of Ratio Mtn and Goodwin Mtn. The map reveals a history of resource extraction through the naming of access routes like Big Foot Mine Rd and State Mine Rd, indicating the importance of mining to this montane region. Water sources are critical in this arid high-country environment, documented here through isolated points like Roadside Spring and Wildhorse Spring, alongside the containment of Keogh Reservoir. The drainage patterns of Beaver Cr and Little Whitetail Cr provide the primary geographic structure for the surrounding forest and the open expanse of Poison Flats.
