1964 Map of Fremont Butte

About this map

Fremont Butte dominates this high desert landscape in Sublette County during the mid-1960s, a terrain defined by sagebrush flats and the winding paths of the East Fork River. The map provides significant historical evidence of early westward travel via the Lander Cut-off, which traverses the center of the sheet and includes the Lander Cut-off Reservoir. This wagon route, an alternative to the main Oregon Trail, remains a visible part of the geography alongside more modern developments like the Fremont Butte Well. Drainage patterns are clearly marked by the meandering Silver Creek to the north and the confluence of Cottonwood Creek and Pocket Creek to the east. The map captures a moment when traditional trails and energy exploration began to overlap in the Wyoming basin.
