Their wagons lurching over sharp boulders up a steep grade, westbound emigrants found a particularly difficult stretch of trail about 40 miles east of South Pass. The late-starting Willie Company of Mormons pulling handcarts suffered terribly here in 1856. For many, the end of the journey was a grave.

Stability can be fleeting in a boom-and-bust economy, especially for racial minorities facing discrimination. African-Americans struggled to earn respect in early 20^th century Wyoming, and building churches in Rock Springs and other towns helped them anchor their lives with a sense of belonging.

Westbound wagon-train emigrants got their first glimpse of the Rocky Mountains when they first saw the blue cone of Laramie Peak, 85 miles away. Snowcapped in early summer, the mountain stayed in sight for a week or more, dominating many diarists’ accounts and foreshadowing drier, more difficult country ahead.

From Union Army soldier to teamster to Guernsey, Wyo., town father, John “Posey” Ryan earned a reputation as an honorable man. But his life’s path took a wrong turn when, believing they had stolen his livelihood, he publicly shot his wife and her daughter to death.

Another high heating bill? A newspaperman wondered why. What he found led the Casper Star-Tribune on a probe in 1984 that revealed how a gas company was passing the cost of its own mismanagement on to Casper customers. It saved residents money, and earned a Pulitzer nod.

In 1854, a year of heavy traffic on the Oregon Trail, Fort Laramie was woefully undermanned, tribes were hungry and tensions were growing. That August, in a dispute over a strayed cow, a reckless young West Pointer ignited a war with the Lakota Sioux that would last a generation.

After flying combat missions in World War II, Tom Bell launched another battle—to preserve western lands. The founder of the Lander, Wyo.-based High Country News managed to keep the publication afloat and conservation in the minds of its readers. His legacy and the magazine continue today.

It may seem surprising that a solitary New York socialite would make Yellowstone safer. But Alice Morris’s love of Yellowstone National Park led to her horseback explorations in 1917, when she chronicled the park’s wonders and detailed changes to improve and standardize trail systems that remain in place today.

In May 1950, Louise Spinner Graf served as foreman of a jury in Green River, Wyo.—practically the first Wyoming jury to include women since 1871. The jury convicted Otto Long of second-degree murder. Afterward, Long’s attorney blamed the outcome on “those damn women.” Women have served successfully on Wyoming juries ever since.

A short line with a short life, the 40-mile-long Wyoming North and South Railroad began quietly during the oil-boom years of the 1920s. It helped the Salt Creek area thrive for a time, but unsound construction, better roads for cars and trucks, bad weather and the Great Depression sealed its demise.
