Ruts carved two to six feet deep in a sandstone ridge on the south side of the North Platte River about a half mile south of Guernsey, Wyo., provide striking physical evidence of the route followed by hundreds of thousands of westbound emigrants the Oregon Trail during the years 1841-1869.

Owen Wister’s enormously popular novel, The Virginian, published in 1902, was set in Wyoming and established the cowboy in American literature as the noble, competent, humorous, laconic hero still familiar today. Wister, a Philadelphian, first came to Wyoming in 1885, looking for stories and better health. He visited the state 14 more times between then and 1900, writing and publishing western stories and books of stories before The Virginian made him famous and rich, and set a pattern for thousands of western novels and films to come.

In the 1820s and 1830s, what’s now western Wyoming was at the center of the fur trade of the northern Rocky Mountains. Indians, trappers and their suppliers met each summer at a big trade fair called rendezvous, where trappers exchanged their season’s beaver pelts for hardware, whiskey and supplies. By 1840, demand for beaver had disappeared and the species had been nearly rubbed out. But the rendezvous supply routes were already becoming the trails that would bind the nation together.

In 1943, Cpl. Leon Tebbetts and three other soldier-artists were among the thousands of troops stationed at the U.S. Army Air Base in Casper. They created 15 murals showing major events in Wyoming history on the interior walls of the Servicemen’s Club. The colorful murals have been well preserved and can still be seen today at the same place—now the Wyoming Veterans Memorial Museum.

As the beaver trade waned in the 1830s, so did economic reasons for an American toehold in the Oregon country, still under joint British-American occupancy. Religion shifted the balance of power, however, when American Protestant missionaries crossed the Rocky Mountains with an eye toward converting the tribes of the Northwest. Soon these men brought their wives with them as well. In 1836, Narcissa Whitman and Eliza Spalding were the first Euro-American women to cross South Pass, and these people became the vanguard of American settlement of Oregon.

Robert Stuart and partners and employees of the fur magnate John Jacob Astor, traveling east in 1812 from the Oregon coast to St. Louis, crossed “a handsome low gap” in the Rocky Mountains in October of that year, after receiving a tip months before about its existence from a Shoshone guide. This marked the discovery by European Americans of South Pass, destined in coming decades to become the main route of American expansion to the West.

Point of Rocks Stage Station, 25 miles east of present Rock Springs, Wyo., was built in 1862 by the Overland Stage Company. The station was attacked and burned at least once by Indians, and stagecoach passengers were supposedly robbed and murdered nearby by the notorious outlaw and onetime stage-line superintendent Jack Slade. Point of Rocks Stage Station has been a school, freight station, store, ranch headquarters and a home. It is one of the only stage stations remaining intact on the Overland Trail. This site is on the National Register of Historic Places.

Nellie Tayloe Ross, a Democrat, was elected governor of Wyoming a month after her governor husband, William Ross, died of appendicitis in the fall of 1924. She ran because of respect for her husband’s Progressive ideas and also as a result of her own ambition. She lost her bid for re-election in 1926, but went on to figure prominently in the leadership of the national Democratic Party. President Franklin D. Roosevelt appointed her to direct the U.S. Mint after he took office in 1933, a job she held for 20 years. She died in Washington in 1977, at the age of 101.

John Richard’s bridge across the North Platte River near present Casper, Wyo. eased the way for thousands of those who traveled the Oregon, California and Mormon trails during the years 1852-1866. Because Richard spoke with a French accent, many people thought his name was Reshaw and began referring to the bridge as Reshaw’s Bridge. A number of diarists, including world traveler Sir Richard Burton, recorded their experiences and descriptions of the bridge and the mixed-race community that thrived at the nearby trading post.

Sheridan, Wyoming first boomed when the Burlington and Missouri Railroad reached it in 1892. Named for a Civil War general and situated in the center of Indian War country, the town became a regional center for business and western culture. Sheridan developed many local processing industries in its first few decades, and also attracted wealthy residents. However, its fortunes have fluctuated with the nation’s demand for nearby natural resources like coal, and the changing economics of agriculture. Today, Sheridan’s unique identity is still rooted in its distinctive culture and scenic location near the Bighorn Mountains.
