Business & Industry

Though the site was an important river crossing on the early frontier, the town of Casper did not begin until 1888, when the Fremont, Elkhorn & Missouri Valley Railroad reached the area. The town immediately became an important shipping point for cattle and wool. The first oil refinery was built in 1895 to process crude oil from the Salt Creek Oil Field, 40 miles to the north. The first true oil boom began after 1910 and lasted through the mid 1920s, and the town’s fortunes have been closely connected to the energy business ever since. In 2010 the city’s population passed 55,000. Casper continues as a retail, medical and energy-industry service hub.

Construction of Buffalo Bill Dam, completed in 1910 six miles west of Cody, Wyoming, was the key that opened about 90,000 acres in northwestern Wyoming to irrigated farming. Its construction was slowed by engineering difficulties and labor strife, but when it was finished stood as an engineering marvel, one of the first concrete arch dams built in the United States and the tallest dam in the world at the time.

Prospectors first struck oil in the Salt Creek Oil Field in northern Natrona County, Wyo. late in the 1880s. The first gusher came in in 1908. The subsequent boom lasted until the late 1920s, peaking in 1923, when the field produced more than 35 million barrels of oil. Tom Wall, who went to work in the field in 1917, stayed for decades and in the 1970s wrote out his memories of life in the oil patch through boom and bust. After 125 years and thanks to new technologies, the Salt Creek Field continues to produce today.

Billy Owen never saw a railroad until he was eight years old. His mother had told him about railroads. But in his mind as he traveled east by wagon train across Wyoming in the spring of 1868, he had imagined railroad wheels that looked something like wagon wheels. They rolled in grooves. Each groove was made by two rails. That meant it took four rails, as he imagined it, to make a track.
