About this map

Upper Valley and Dry Valley divide this portion of the Caribou National Forest, where the high-altitude terrain is defined by parallel ridges like the Rasmussen Ridge and the Wooley Range. The Blackfoot River winds through the center of the sheet, constricted by a geographic feature known as The Narrows near a small Wier. Early ranching and administrative presence is visible at the Stocking Ranch and the nearby Trail Guard Sta, suggesting a landscape of seasonal grazing and forest management at the midpoint of the century.

Water sources are critical to the valley floor, evidenced by the numerous named springs and creeks such as Diamond Creek, Bacon Creek, and Campbell Spring. Small-scale exploration is noted by several Prospect markers in the western canyons, while the Dry Valley Trail provides a glimpse into the primitive transportation network used to traverse the high basins between the Caribou Range and the Webster Range.
