The Greybull Hotel, built in 1916, was the first and largest of its kind in downtown Greybull, Wyo., to be constructed with brick and concrete. Its main commercial space has served as a bank, a clothing store and a bar; during Prohibition there was a speakeasy in the basement. The hotel’s location--at the corner of Greybull Avenue and Sixth Street and at the intersection of Wyoming Highway 14 and Wyoming Highway 16/20—was of primary importance in the early days and remains so today.

In 1995, current owners, Doug and Larita Brown bought the property, which is listed in the National Register of Historic Places, in 1995.

As many as half a million people crossed what’s now Wyoming in the mid-19th century before the transcontinental railroad was built. Their trails followed the North Platte and Sweetwater rivers west to South Pass, after which they divided into various routes bound for Oregon, Utah or California. They were making the journey of a lifetime, on routes blazed by Indians and trappers, and then worn deep and wide by thousands of wagons and perhaps millions of draft animals. These trails remain largely unchanged in Wyoming. Their white-topped wagons still hold an important place in the national imagination.

Washakie County, formed in 1911 and named for the Shoshone Chief Washakie, continues to rely upon energy and agriculture as its main industries.
