Ratio Mountain dominates this mid-1980s landscape within the Deerlodge National Forest, where high-elevation drainage patterns define the territory. The map details a transition from the wooded heights of Goodwin Mountain and the Bull Mountain Game Range down to the open Whitetail Valley. Resource extraction is evident through several noted prospects and a mine shaft located near the State land boundary, suggesting a history of small-scale mineral exploration. Water sources are critical in this environment, marked by named features like Wildhorse Spring and Roadside Spring, which feed into a complex network of streams including Beaver Creek and the South Fork Beaver Creek. The presence of Poison Flats and Whitetail Basin indicates a geography carved by seasonal runoff and distinctive local landmarks used by generations of land managers and outdoorsmen.
