The California Trail carried over 250,000 gold-seekers and farmers to the gold fields and rich farmlands of California during the 1840's and 1850's, the greatest mass migration in American history. Today, more than 1,000 miles of trail ruts and traces can still be seen in the vast undeveloped lands between Casper Wyoming and the West Coast, reminders of the sacrifices, struggles, and triumphs of early American travelers and settlers. More than 240 historic sites along the trail will eventually be available for public use and interpretation. The trail passes through the states of Missouri, Kansas, Nebraska, Colorado, Wyoming, Idaho, Utah, Nevada, Oregon, and California.

The Uinta County Museum is located in the historic Carnegie building, completed in 1906. A lovely example of Classical Revival architecture, the building was designed by New York architect Albert Randolph Ross (who also designed a Carnegie Library in Washington, D.C.). In 2008, an expansion of the building was completed. Designed by Jackson architect Kurt Dubbe, the new building echoes the historic features of the original structure. Their mission is to collect, preserve, and interpret the history of Uinta County and the surrounding region, and to make our collections available to the public.

The Museum reflects the history of Crook County. Permanent exhibits include Indian artifacts, cowboy artifacts and pioneer artifacts dating from 1875.

Led by Brigham Young, roughly 70,000 Mormons traveled along the Mormon Pioneer Trail from 1846 to 1869 in order to escape religious persecution. The general route is from Nauvoo, Illinois, to Salt Lake City, Utah, covering about 1,300 miles. The Mormon Pioneer Trail travels through five states over both public and private land.

As the harbinger of America's westward expansion, the Oregon Trail was the pathway to the Pacific for fur traders, gold seekers, missionaries and others. Beginning in 1841 and continuing for more than 20 years, an estimated 300,000 emigrants followed this route from Independence, Missouri to Oregon City, Oregon on a trip that took five months to complete. The 2,170 mile long trail passes through Missouri, Kansas, Nebraska, Wyoming, Idaho and Oregon.

The Pony Express National Historic Trail was used by young men on fast paced horses to carry the nation's mail across the country, from St. Joseph, Missouri to Sacramento, California, in the unprecedented time of only ten days. Organized by private entrepreneurs, the horse-and-rider relay system became the nation's most direct and practical means of east-west communications before the telegraph. Though only in operation for 18 months, between April 1860 and October 1861, the trail proved the feasibility of a central overland transportation route, and played a vital role in aligning California with the Union in the years just before the Civil War. Most of the original trail has been obliterated either by time or human activities. Along many segments, the trail's actual route and exact length are matters of conjecture. However, approximately 120 historic sites may eventually be available to the public, including 50 existing Pony Express stations or station ruins.

The Grand Encampment Museum, located in Encampment, Wyoming, preserves history with its collection of over a dozen historical buildings filled with artifacts representing the timber, mining, and agricultural history of the Encampment valley.

This unique historic place preserves and interprets one of America's most important locations in the history of westward expansion and Indian resistance. Established in 1834, Fort Laramie began as a fur trading post. By the 1840s, wagon trains rested and resupplied here, bound for Oregon, California and Utah. In 1849 as the Gold Rush of California drew more westward, Fort Laramie became a military post, and in 1876, Fort Laramie served as an anchor for military operations, communication, supply and logistics during the "Great Sioux War." Fort Laramie closed in 1890.

Since the early days of the cattle industry and the advent of the Union Pacific Railroad, Cheyenne and Wyoming have played an integral part in the development of the West. The Old West Museum gives residents and visitors to Wyoming an opportunity to discover and experience our heritage through exhibits, educational programs and research opportunities.
