Transportation

Poetry, shouts and song—year after year, reactions were similar when Oregon Trail emigrants managed the steep climb up Prospect Hill, also called Ryan Hill, on the road from the North Platte to Independence Rock. The sight of range after range of mountains greeted them—a sweeping view of new country.

About 20 miles west of present Casper, Wyo., the Oregon Trail wound through a gap between two rocky hogbacks. Emigrants called it Rock Avenue. In the 1960s and 1970s, road builders blasted away some of the rocks. Part of the pioneer flavor of the place was lost, but much remains.

After leaving the North Platte River near present-day Mills, Wyo., Oregon Trail travelers journeyed 10 miles or so through windswept, sometimes rocky terrain before coming through a shallow pass, now known as Emigrant Gap. Beyond it, at the base of a hill lay Mineral Lake, an alkali pond.

The amazing sight of Ayres Natural Bridge, a natural limestone arch across La Prele Creek near Douglas, Wyo., inspired numerous Oregon Trail emigrants to comment in their diaries. California-bound Cephas Arms on July 4, 1849, described it as “one of the wildest scenes I ever beheld.”

About 70 miles northwest of Fort Laramie, the Oregon Trail crossed La Prele Creek, flowing north from the Laramie Range toward the North Platte River a few miles away. On a high bluff above the creek mouth the U.S. Army in 1867 would build Fort Fetterman, which became an important supply base in the wars with the Cheyenne and Lakota Sioux in the following decade.

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.

Three-year-old Ada Magill of Kansas, died of dysentery in 1864 on the Oregon Trail west of present Glenrock, Wyo. The Magills were bound for Oregon. In 1912, road surveyor L. C. Bishop moved the grave to a site nearby, where it is now marked by the Oregon-California Trails Association.

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.

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. 

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.
