Euro-Americans first described what’s now Sublette County in western Wyoming early in the 1800s, when it was a hub for the Rocky Mountain fur trade. Cattle ranchers followed the fur trappers. Soon, tie hacks arrived to cut timber for railroad ties. The county’s first successful oil well was drilled in 1907, and oil and gas have been important to the county ever since. In the early 1990s one of the world’s largest gas fields was discovered south of Pinedale, the county seat. County residents continue to work to balance energy booms with the conservation measures needed to keep life good and to keep tourists coming back.
