Natrona County’s Salt Creek Field is best known of Wyoming’s early oil fields, but five others—two in Park County and one each in Hot Springs, Niobrara and Converse counties—played important roles in the state’s 20th century transformation from an agricultural to an industrial economy.

Since prehistoric times, people’s lifestyles in what became Natrona County have depended on their livelihoods. Casper was founded in 1888, and county was formed in 1890, shortly before Wyoming became a state. First cattle, then sheep and after 1910, the oil and refining business dominated. An Army Air Corps training base near Casper brought another boost in World War II. Casper College was founded in 1945. Since then, the county has continued to ride the booms and busts of the energy business, but with cultural, health-care and education opportunities growing all the while.
