Samuel H. “Doc” Knight taught geology at the University of Wyoming in Laramie, Wyo. from 1916 until his retirement in 1963. For a decade he was the only geology teacher, but as his classes began to grow in size and popularity the geology department expanded into a nationally recognized program. He established the university’s science camp in the mountains west of Laramie and revitalized the university’s geological museum. Knight taught an estimated 10,000 students throughout his career and was known to many “Mr. Geology of Wyoming.”

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.

The youngest child of an Afton, Wyo., dairy farmer, Rulon Gardner wrestled his way to international fame, defeating three-time champion Aleksandr Karelin in Greco-Roman wrestling at the 2000 Summer Olympics in Australia. However, Gardner’s quest for more Olympic gold has been beset by numerous obstacles, including a toe amputation, a plane crash and bankruptcy.

Early Wyoming was seen as a hardscrabble place. But after 1900, dude ranches showed off Wyoming’s mountain scenery, fishing, hunting and hospitality, and thanks to the elite guests’ taste-making powers, Wyoming and the West became associated less with cold wind and distance and more with romantic glories.

Wind is constant in Wyoming, but ways of harnessing its power have changed substantially over time, from wooden windmills pumping water for railroads and livestock, through small, wind-charged battery plants on 1920s ranches to the huge wind turbines spiking our skylines today.

Rock Springs, Wyo. traces its origins to a coal mine established there in 1868 to serve the still-building Union Pacific Railroad. Ever since, the town has been enriched by the people who came from around the world to live and work there—in coal mines, on the railroad and, in recent decades, in trona mines to the west and the oil and natural-gas fields to the north. Rock Springs boasted 56 nationalities by the 1920s. Its political and economic fortunes have closely followed all these industries’ cycles of boom and bust.

When the U.S. Army in 1866 sent troops to build a string of forts along the Bozeman Trail north from the North Platte River to the Montana gold fields, Lakota, Cheyenne and Arapaho tribes in that country reacted angrily. For two years, the tribes harassed and attacked the soldiers and travelers on the trail. After the Treaty of Fort Laramie in 1868, the Army withdrew, the Indians burnt the forts and for a few years, until hostilities started up again in the mid-1870s, the tribes the country largely to themselves.

Celebrated Wyoming sculptor Robert Russin created works of all sizes in bronze and stone. Though not a native of the state, Russin lived and taught in Laramie for sixty years, and his work continues to influence artists, students, collectors and the public.

Robert D. Carey was the first Wyoming Governor to be elected by vox populi (the voting public). He served from January 6, 1919 to January 1, 1923 and his term of office was marked by his establishment of sound financial footing for the state and an increase in state revenue.

As soon as Europeans came to the coasts of North America, they began trading for furs with the people who already lived here. On the first of June 1834, about 60 men and a caravan of horses and pack mules splashed across the Laramie River. They were headed for rendezvous in the mountains — the big summer fur-trading fair — and they were late.
