County of sublette

History & Founding

Sublette County occupies a vast and stunning corner of western Wyoming, a place where the rugged beauty of the Rocky Mountains dominates the landscape. Established in 1917, it was carved out of parts of Lincoln and Teton counties, reflecting the ongoing expansion and settlement of Wyoming. The name honors Michel Sublette, a French-American fur trader and explorer who played a significant role in the Rocky Mountain fur trade during the early 19th century. Sublette’s expedition in 1823-1824, though fraught with hardship and ultimately unsuccessful in finding a viable beaver trapping route, helped chart the region and contributed to its eventual settlement. An interesting anecdote from the county’s early days involves a lost prospector named Silas Bartlett, who, during a particularly harsh winter in the 1890s, reportedly survived for weeks by living off pine nuts and snowshoe hares, becoming something of a local legend. The county’s formation marked a period of increasing agricultural and ranching activity in southwestern Wyoming, contributing to the state’s overall development.

Geography & Landscape

The county's location places it squarely within the Wyoming Basin, characterized by its high elevation and arid climate. It encompasses a staggering 4,882 square miles, making it the second largest county in Wyoming by area. The landscape is overwhelmingly mountainous, dominated by the Wind River Range to the east and the Gros Ventre Range to the west. The Snake River and its tributaries, including the Gros Ventre River and the Hoback River, provide vital water sources. Numerous lakes, such as Green River Lake and Fontenelle Reservoir, dot the landscape, providing recreational opportunities. The climate is characterized by long, cold winters and short, warm summers. Average annual precipitation is relatively low, primarily falling as snow. Notable natural features include the Wind River Range’s towering peaks, the expansive sagebrush flats, and the unique geological formations sculpted by glaciers and erosion.

Economy & Communities

Three primary communities define Sublette County: Pinedale, the county seat, Big Piney, and Marbleton. The economy is primarily driven by tourism, ranching, and energy development. Tourism flourishes due to the county's proximity to Yellowstone and Grand Teton National Parks, attracting visitors eager to experience outdoor recreation like hiking, fishing, and hunting. Ranching remains a significant aspect of the local economy, with numerous cattle and sheep ranches operating throughout the county. Natural gas extraction is a major industry, providing employment for a substantial portion of the population. Notable employers include Occidental Petroleum, ConocoPhillips, and various ranching operations. The overall character of the area is distinctly rural, with a strong sense of community and a deep connection to the land.
