The federal government finally entered the irrigation business in 1902, after it became clear that large infusions of public funds were needed to build projects big enough to be effective in the arid West. The eventual result was a dozen dams across Wyoming, but crop agriculture here remains scarce. 

Susan Wissler, elected mayor of Dayton, Wyo., in 1912, was Wyoming’s first woman mayor and possibly the second in the nation. Promising to act “without fear or favor,” she served three terms, with some success cleaning up local saloon and gambling elements, all while running her own millinery and dry-goods business.

In 1919, 50 years after Wyoming women won the right to vote, Congress finally passed the 19th Amendment to the Constitution, granting women the same rights nationwide. Before the measure could become law, however, 36 of the 48 states would have to ratify it. Wyoming suffragists organized for a final push.

The National Park Service’s Mission 66, initiated in 1956, modernized facilities, built new ones, built roads and added dozens more parks and historic sites. In Wyoming, architects designed buildings meant to enhance visitors’ experiences while protecting the wonders they came to see. The results recast Americans’ relationships with natural beauty.

Esther Hobart Morris, appointed justice of the peace in South Pass City in 1870, was the first woman in the nation to hold public office. While she is notable for that and for her longtime advocacy for women’s rights, much of her fame comes from something she almost certainly didn’t do.

Suffragist and temperance orator Theresa Jenkins delivered a key address at Wyoming’s statehood celebration on July 23, 1890. Later, she spoke widely in Colorado and other states, promoting Wyoming’s example in women’s rights, and spoke at the 1920 W.C.T.U. World's Convention in London.

Wyoming’s trails, roads and highways follow centuries-old Native American hunting and trade routes. For generations, Shoshone, Arapaho, Cheyenne, Ute, Lakota and Crow people gathered plants, visited family and tracked game along watercourses and over mountain passes in the seasonal subsistence patterns of their lives.

Not only was Wyoming Territory the first government in the world to pass a law allowing women unrestricted voting rights—the territory and state can claim a number of other firsts as well. See the list for dozens more firsts for Wyoming women.

Estimates of the numbers of women who voted in the principal towns of Wyoming Territory, and a review of the methods used to make those estimates.

Some delegates drawing up a new state constitution in 1889 feared that, once Wyoming’s statehood came before Congress, continuing to allow women to vote would jeopardize Wyoming’s chances of becoming a state. And they were right.
