The 1880s cattle boom seemed to promise a rich future for Alexander Swan, who amassed 4.5 million acres in southeastern Wyoming to graze 100,000 head. His extravagant tenure ended quickly—but the ranch lasted generations.

As an agricultural depression swept Wyoming, one of Powell’s banks temporarily closed. The owner of a second, S.A. Nelson, ordered tellers to stack cash in plain sight to calm jittery depositors. Thirty-six banks failed in Wyoming in 1924 alone. Confidence eventually returned—but only very slowly.

First described in 1842 by explorer John C. Fremont, Warm Springs, near present Guernsey, Wyo., is one of the most famous water holes on the Oregon-California Trail. Many emigrants stopped here to rest, bathe, wash clothes and carve their names on nearby sandstone bluffs.

On Oct. 5, 1857, a band of Mormon militia attacked U.S. Army supply wagons at Simpson’s Hollow west of what’s now Farson, Wyo., burning 26 wagons and stampeding army mules. The army was advancing on Utah to enforce federal law there, and the Mormons resisted—all part of the bloodless Utah War.

Wealthy artist, hunter and conservationist A.A. Anderson was named superintendent of the new Yellowstone Forest Reserve in 1902. His love for wildlife habitat clashed with local timber and grazing interests, however, and, after much controversy, he lost his job. Wyoming and the nation might have benefitted if he’d found a way to bridge that gap.

The lure of the the California Gold Rush led even a prosperous wagonmaker like Daniel Lantz of Centreville, Ind. to try his luck. But on the trail in what’s now southwestern Wyoming, illness struck him. Months later, his wife and five children at home learned he never made it through.

Three total solar eclipses have crossed Wyoming since territorial times—in 1878, 1889 and 1918. Two in particular drew prominent astronomers and scientific discoveries. These are especially interesting now, with the August 21, 2017 eclipse likely to draw huge crowds to a very different Wyoming from the one that last saw moon shadows in daytime.

Out of nearly 200 people who died from murder or other homicides on the Oregon Trail in the mid-1800s, only one lies in a grave with a known location. Missourian Ephraim Brown, a leading figure on a wagon train bound for California, was killed near South Pass in 1857 in what appears to have been a bitter family dispute. Details, however—who killed him, why and how—are frustratingly sketchy.

No logging, no grazing—even no trespassing? The Yellowstone Timber Land Reserve, the first land to be set aside in what evolved into today’s National Forest system, had a distinctly different character from its successors. Here’s why.

Wyoming soldier, artist, bugler and wolf killer George Ostrom joined the National Guard in 1913 and in 1918 found himself serving with an artillery regiment in the Great War. While in France he sketched vivid combat scenes but is best remembered for his design of Wyoming’s famed bucking-horse logo, modeled on his beloved sorrel, Redwing.
