|Casper is the county seat of Natrona County, Wyoming. With a population of 49,644, Casper is the second largest city in Wyoming, according to the 2000 census. Casper is nicknamed "The Oil City" and has a long history of oil boomtown and cowboy culture, dating back to development of the nearby Teapot Dome.
Casper is located in east-central Wyoming at the foot of Casper Mountain, the north end of the Laramie Mountain Range, along the North Platte River. The city was established east of the former site of Fort Caspar, which was built during the mid-19th century mass migration of land seekers. The area was the location of several ferries that offered passage across the North Platte River in the early 1840s.
In the rugged Old West era, Casper promised adventure to all who traveled its famous trails. The same sense of free-wheeling adventure still draws visitors to Wyoming's Adventure Capital. With one foot in the past and an eye toward the future, Casper is a year-round destination that offers the very best in historical, recreational, cultural and entertainment experiences.
