Hanna, Wyo., best known for its coal mines, was founded in 1889 by the Union Pacific Coal Co. as a company town. It has survived mining disasters and a long cycle of booms and busts. The last mines around Hanna closed in the mid-2000s. The town survives today as a bedroom community, with hopes of future mineral development.

Bob David, an adopted boy reared by a well-to-do Wyoming family, never felt he truly belonged until he joined the military and went to France during World War I. He served in an artillery unit and survived numerous onslaughts during battle as well as a severe bout of the flu during the 1918 pandemic, which occurred as he was returning home. He recounted his experiences in a long manuscript and other items that became the core of the Casper College Western History Center. Bob David died in 1968.

Prospectors first struck oil in the Salt Creek Oil Field in northern Natrona County, Wyo. late in the 1880s. The first gusher came in in 1908. The subsequent boom lasted until the late 1920s, peaking in 1923, when the field produced more than 35 million barrels of oil. Tom Wall, who went to work in the field in 1917, stayed for decades and in the 1970s wrote out his memories of life in the oil patch through boom and bust. After 125 years and thanks to new technologies, the Salt Creek Field continues to produce today.

Elected to fill out the unexpired term of Gov. DeForest Richards in 1904, Bryant B. Brooks was re-elected to another term in 1907. He was also the first governor to live in the newly complete governor's mansion.

Construction of Buffalo Bill Dam, completed in 1910 six miles west of Cody, Wyoming, was the key that opened about 90,000 acres in northwestern Wyoming to irrigated farming. Its construction was slowed by engineering difficulties and labor strife, but when it was finished stood as an engineering marvel, one of the first concrete arch dams built in the United States and the tallest dam in the world at the time.

Notorious outlaw Butch Cassidy and his Wild Bunch frequently crossed and hid out in Wyoming when on the run from the law. Cassidy’s 18-month incarceration at the Wyoming State Prison in Laramie, 1894-1896, is a definite fact. Other than that, stories place him and his gang all over the map, from Sundance to Brown’s Hole, and Powder Wash near Baggs to Hole in the Wall near Kaycee. Stories persist as well that Cassidy returned to Wyoming decades after his reported death in Bolivia in 1908, but no hard evidence has yet turned up.

Was she a hard-drinking, swashbuckling mule skinner and Indian fighter? Or an alcoholic prostitute, stuck in menial jobs in a life both dreary and mundane? Calamity Jane's life is two stories: the facts of her biography, and the romantic tales that came to comprise the Calamity Jane legend.

Coal, railroads and oil have helped make Campbell County, Wyo., the second wealthiest county in the state, and the county’s coal mines are the largest in the world. Though coal production has begun to fall slightly in recent years, mining continues to be the main engine of the Campbell County economy. The county’s history is rich in Paleo-Indian and bison-bone discoveries as well.

Beautiful Carbon County in south-central Wyoming was established in 1868 and named for its coal. Since fur-trade days, through coal, copper, cattle, sheep, uranium, coal again, natural gas and wind power, booms, busts, and new booms have dominated the economy. The Union Pacific Railroad has by contrast offered a steadying influence, as has the state prison in Rawlins, the county seat. And the North Platte River, locals say, offers the best trout fishing in the world.

Founded in 1868, the short-lived town of Carbon provided crucial coal supplies for the Union Pacific Railroad. Its rough reputation was boosted in 1881, when a mob of miners pulled Dutch Charley Burris, accused of the murder of a popular lawman, from a train and hanged him from a telegraph pole. Many Finnish men worked in the coal mines until 1902, when the mines closed. Today, there are only a few ruins to mark the site, but the Carbon Cemetery has been recently refurbished and is still being used.
