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.

The Sixth Crossing of the Sweetwater offered wagon-train emigrants good water again after 16 dry and dusty miles. Most camped at the crossing. Here, in 1856, 500 members of the Willie Handcart company, most of them Mormon converts from England, were found starving, freezing and dying by rescuers from Salt Lake City.

In 1862, Charlotte Dansie and her family sailed from England with hundreds of other Mormon converts, then gathered with others near Omaha to set out for Salt Lake—all while having a difficult pregnancy with her eighth child. Her descendants managed to relocate her grave in 1939 near Pacific Springs.

Among the many branches and variants of the Oregon Trail was the 35-mile Seminoe Cutoff, which allowed travelers to avoid the last four crossings of the Sweetwater River as well as the difficult climb over Rocky Ridge. Pioneer Sarah Thomas is buried along the route.

In July 1862, a large train of 80 wagons was passing through mountains in what’s now western Wyoming when, within a matter of days, serious troubles led to the deaths of two women and their infants. Elizabeth Paul’s grave remains at the site under a tall pine.

Ever see the bucking horse and rider? In Wyoming you can’t miss it. The logo appears everywhere—license plates, web pages, the university, military insignia and all kinds of signage and merchandise. Ever wonder where it came from? For starters, try France—and Lander.

The main branch of the Oregon Trail crossed the Big Sandy River at present Farson, Wyo. State Highway 28 running southwest from Farson continues to parallel the route. Swales are often visible alongside the highway, sometimes to the right, sometimes to the left.

Whether Oregon Trail emigrants took the westbound Sublette Cutoff at Parting of the Ways or the more southerly route toward Fort Bridger, the next water they had to cross was at Little Sandy Creek, running south through the sandy, sagebrush plains west of the Continental Divide.
