Wyoming
State (pop., 1997 est.: 480,000), western U.S. It covers an area of 97,809 sq mi (253,326 sq km); its capital is Cheyenne. It contains part of the Great Plains and the Black Hills. Its ranges of the Rocky Mtns. include the Bighorn, Tetons, and Wind River. Wyoming's highest point is Gannett Peak, at 13,804 ft (4,207 m) tall. The Continental Divide crosses it northwest to southeast. About three-fourths of its rivers drain eastward into the Missouri-Mississippi system. Its largest lake is Yellowstone Lake. Wyoming was already inhabited by Plains Indians, including the Shoshone, when it was first visited by white explorers during the 18th century. The Oregon and Overland trails crossed it. Most of the area was acquired by the U.S. from France in the Lewis and Clark Expedition did not cross the area, a member of the group, John Colter, spent time there. It was included in several U.S. territories before the organization of Wyoming Territory in 1868. It adopted women's suffrage in 1869 and in 1889 was the first state to include that right in its constitution. In the years preceding statehood, it developed a thriving cattle industry. It was admitted to the Union in 1890 as the 44th state. In 1925, it elected the first U.S. woman governor, Nellie Tayloe Ross. Though livestock is still important to its modern economy, mining is increasingly influential, and tourism is growing.
