In 1869 Wyoming extended suffrage to women, at least partially in an attempt to garner enough voters to be admitted as a state. In addition to being the first U.S. state to extend suffrage to women, Wyoming was also the home of many other firsts for U.S. women in politics. It had the first female court bailiff and the first female justice of the peace in the country. Wyoming was also the first state in the Union to elect a woman governor, Nellie Tayloe Ross in 1925.

Wyoming is generally considered an arid state with much of the land receiving less than 10 inches of rainfall a year. Consequently, the land supports few opportunities for farming. Ranching however is widespread, especially in areas near the numerous mountain chains. There are several major mountain ranges in the state, all of them are part of the Rocky Mountains. The Snowy range in the south central part of the state are an extension of the [Colorado] Rockies in both geology and appearance. The Wind River Range in the west central part of the state are remote and also have the highest peak Gannett Peak, in the state. The Big Horn Mountains in the north central are somewhat isolated from the bulk of the rest of the Rocky Mountains. Finally the Teton Range in the northwest extend for 50 miles and represent the most impressive section of mountains in the state and are home to the second highest peak Grand Teton and Grand Teton National Park which preserves the most scenic section of the Teton range.

Several rivers begin or flow through the state including the Yellowstone River, Powder River and the Snake River.

The Continental Divide which runs through most of North America splits in two in the south central part of the state. The waters that flow or precipitate into this area known as the Great Divide Basin do not flow to any ocean. Instead due to the overall aridness of Wyoming, they simply sink into the soil or evaporate.

Wyoming sports the lowest population density of the continental 48 states; however, non-contiguous Alaska's is lower.
