About this map

The Gros Ventre Range and Sawtooth Range dominate this 1967 survey of Sublette County, marking the high-altitude divide between the Teton National Forest and Bridger National Forest. The landscape is defined by its dramatic relief, reaching its height at Tosi Peak and the sharp turn in the terrain known as The Elbow. Significant water features like Clear Creek and Tosi Creek drain the western slopes, while the Big Twin Water Dog Lakes sit in the southeastern corner.

Industrial activity is sparse in this wilderness, though a lonely Drill Hole on a Jeep Trail near Tosi Creek hints at natural resource exploration during the mid-century. The map is a record of a high-country frontier just as it was being formally managed and surveyed, showing an intricate network of a Pack Trail and jeep tracks that provided the only access through features like Coyote Basin and across Elk Ridge.
