Oil seeps were reported often in the early 19th century in what later became Wyoming; it was sold, for example to Oregon Trail travelers for wagon lubricant. The first producing well in Wyoming Territory was drilled in 1883 at Dallas Dome southeast Lander. Perhaps the state’s best-known historic oil producing region is the Salt Creek Field, north of Casper, which was one of the world’s largest-producing fields in the 1920s. Oil remains an important part of Wyoming’s economy and culture today, and the state is ranked high among the top national producers.
Pinedale, Wyo. was founded in 1904, incorporated in 1912 and became seat of brand-new Sublette County in western Wyoming in 1921, when the town still boasted only about 100 people. Despite its isolation, the town survived well through the 20th century on ranching and tourism. It began to change more quickly in the early 1990s, as development sped up in the nearby Pinedale Anticline and Jonah natural gas fields. Today, with more than 2,000 people, the town works hard to keep its traditions while dealing with steady, industrial growth.
