In Wyoming, dry farming—growing crops without irrigation--began to become popular in the early 1900s. Vernon T. Cooke, first state director of dry farming, was extremely influential in promoting the method. Today, the University of Wyoming’s experimental agricultural station continues to develop dry farming techniques. 

Wyoming’s sheep business never had the fame or cachet of Wyoming’s cattle business, but at the turn of the last century sheep raising was more widespread and probably more lucrative. Cattlemen, however, reacted violently to sheepmen’s entry onto the public range, and for a time deadly raids by cattlemen on flocks, sheepdogs and sheepherders were chronic. A gradual decline in wool and lamb prices since the 1920s has left only about a twentieth as many sheep on Wyoming ranges now as there were in 1909.

Mary Hughes was just 17 years old in 1908 when the No. 1 Mine exploded twice in one day—and for the second time in five years—in Hanna, Wyo. Her story shows the devastating impact that coal mine accidents had on families like the Hugheses across Wyoming’s mining communities, and reveals her determination to survive disaster.

Devils Tower, a basalt column rising 1,267 feet above the nearby Belle Fourche River, was the nation’s first National Monument and remains important to tourists and the many tribes that hold it sacred.

The Durlacher House in Laramie, Wyo. was built in 1878 for Civil War veteran Simon Durlacher. Durlacher arrived in town a decade earlier and just one month before the Union Pacific Railroad tracks reached Laramie. The house, designed by architect Charles Klingerman in late-Victorian Queen Anne style, was also used as a church and now is used by a private business. The Durlacher House is listed on the National Register of Historic Places.

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.

Bill Carlisle robbed passengers on the Union Pacific Railroad three times in 1916 and once more in 1919, after escaping from the state penitentiary in a box of shirts. In 1936 he was paroled and opened a café and tourist court in Laramie, and later wrote a book about his remarkable life.

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.
