Encyclopedia | 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.
Encyclopedia | Samuel H. “Doc” Knight taught geology at the University of Wyoming in Laramie, Wyo. from 1916 until his retirement in 1963. For a decade he was the only geology teacher, but as his classes began to grow in size and popularity the geology department expanded into a nationally recognized program. He established the university’s science camp in the mountains west of Laramie and revitalized the university’s geological museum. Knight taught an estimated 10,000 students throughout his career and was known to many “Mr. Geology of Wyoming.”
Encyclopedia | Como Bluff in Carbon County and Albany County, Wyo., is the location of one of the world’s richest quarries of Jurassic dinosaur bones. Paleontologists found excellent dinosaur fossils in greater quantity here in the late 19th century than had ever been known before. These included Allosaurus, Diplodocus and Apatosaurus. Many of these specimens are still on display at the Peabody Museum at Yale University, the Smithsonian Institution’s National Museum of Natural History in Washington, D.C., and the American Museum of Natural History in New York City. The site is seldom quarried today, as most of the bones have been removed. Como Bluff is listed on the National Register of Historic Places.

Encyclopedia | The basin of the North Platte River takes up the southeastern quarter of Wyoming, plus a finger of land along the tributary Sweetwater River in the center of the state. The courses of the North Platte and Sweetwater determined early fur-trade and emigrant routes. Since that time, the basin’s water and other resources have continued to draw industry, stock raising, dams and irrigation—and people.
