Since it first entered the state in 1890, the Burlington Railroad has helped connect Wyoming with the world. Burlington officials were drawn here by Wyoming’s marketable natural resources and by its geography: Wyoming offered the best routes for transcontinental lines from the Midwest and South to the Pacific Northwest.

In October 1969, University of Wyoming Head Coach Lloyd Eaton dismissed 14 Black football players from his team when they showed up at his office wearing black armbands over their street clothes, to protest what they saw as racist policies of Brigham Young University. The incident sparked widespread controversy and swung the national news spotlight on Wyoming.

Wyoming’s bone-dry Bighorn Basin is isolated by its surrounding mountains and watered by crucial rivers and streams. Its history and natural history are rich with discoveries of dinosaurs, oil and gas, and with the traces of its occupants—American Indians, ranch and farm families, railroad families and oil workers.

When completed in June 1909 on the North Platte River, 47 miles southwest of Casper, the granite Pathfinder Dam was a triumph of early 20th century design. It was one of the earliest federal Reclamation Service dams in the West, and convinced agency officials of their ability “to do great things.”

Two battles on July 26, 1865 near Platte Bridge Station near present-day Casper, Wyo., are best understood in the context of tribal response to the Sand Creek Massacre the previous November. Twenty-eight U.S. troops were killed that day including Lt. Caspar Collins, for whom Fort Caspar and the town of Casper were later named.

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.

In March 1866, when whites and Indians together at Fort Laramie mourned the death of Mni Akuwin, daughter of Spotted Tail, chief of the Brulé Lakota, a colonel at the post hoped it was a sign of peace between the peoples. Peace hopes were shattered later that spring however, by the arrival of hundreds of troops to build forts on the Bozeman Trail, and two more years of bitter warfare followed. Finally in 1868, the tribes of the northern plains gathered at the fort and signed a treaty, ending the war—for a while.

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.

Teton County, Wyo., is well-known for its spectacular mountain scenery and for its opportunities to climb, hike, bike, fish, hunt and ski. In the early days, though, travel was much more difficult and few people lived in the area. Grand Teton National Park and part of Yellowstone, the first national park, are located within the boundaries of Teton County. The parks draw millions of visitors each year.

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.
