At Red Buttes, west of present Casper, Wyo., Oregon Trail travelers left the North Platte River and started for the Sweetwater and the Continental Divide. Long a boundary marker for tribes, the spot quickly became well known to emigrants for its beauty and for marking a new stage of the journey.

When pilots on United Airlines Flight 409 took a shortcut in bad weather en route from Denver to Salt Lake City in October 1955, the plane crashed into Medicine Bow Peak and 66 people died. It was the worst airline disaster up to that time, and its cause is still unknown.

In 1988, following extensive research regarding her identity, 1852 Oregon Trail traveler Quintina Snodderly’s remains were re-interred where they had been found in 1974 on private land east of present Casper, Wyo., as part of the Oregon-California Trails Association project to preserve graves of trail travelers.

Frederick Fulkerson, 17, died in 1847 on the Oregon Trail after becoming exhausted and ill from swimming his family’s livestock across the North Platte River near present Casper, Wyo. His grave, located on state land near Devil’s Gate, is one of the oldest identified graves along the trail. 

Many Oregon Trail diarists noted the distinctive, conical shape of 70-foot-high Knob Hill, southwest of present Douglas, Wyo., and compared it to a sugar loaf; others whetted their knives on rocks at its base. British travel writer Richard Burton was skeptical of the tale that Brigham Young had preached a sermon there.

On a jittery night in 1864, a lone warrior stole three horses from a California-bound wagon train west of present Glenrock, Wyo. Early next morning, emigrant Martin Ringo died from an accidental gunshot. His grave is still there, on private land. Johnny Ringo, his son, was later a famous outlaw. 

In the early 1900s, Jewish families came from eastern cities to Goshen County, Wyo., seeking a better life in the West. They farmed, raised families, founded schools and worshiped in private homes. Many were discouraged by the harsh farm life, however, and nearly all left by the 1930s.

Joseph Stimson came to Cheyenne in 1889 to take portraits. In 1900, the Union Pacific hired him as a publicity photographer, with wide leeway to choose his subjects. Soon, his agricultural, industrial and scenic views won him a national reputation. The Wyoming State Archives holds a collection of 7,500 Stimson negatives.

The trapper and guide Kit Carson traversed what’s now Wyoming dozens of times. Of one of those trips we have a close account—1842, when the careful, competent Carson guided a brash young Lt. John C. Frémont of the Topographical Engineers up the old fur-trade route to South Pass.

When a party of Lakota Sioux raiders attacked a small wagon train of Shoshone, white and mixed-race people in 1868, eight-months-pregnant Woman Dress Lamoreaux stopped the skirmish when she climbed from a wagon and threatened the attackers with drastic consequences from her brother, Gall—their war chief—if they continued the fight.
