The final Wyoming Territorial Legislative Assembly created Weston County in March 1890. Thirty years later, the discovery of oil at Osage, Wyo., halfway between the county seat of Newcastle and the small town of Upton, led to a number of cyclical economic booms and busts. Today, the county’s industries include agriculture and oil refining.

Businessman, family man, territorial and state governor, U.S. Senator: Francis E. Warren succeeded in all of these roles, but he is best known for long service in the U.S. Senate on behalf of Wyoming. A Massachusetts native, Warren arrived in Cheyenne in 1868, when the city was still a mass of tents and other temporary structures, and quickly became involved in its business and politics. By around 1900 he was Wyoming’s most powerful Republican, and ran his party’s so-called Warren Machine for decades by patronage and pork-barrel politics.

Frank Lucas took over as acting Governor upon Governor Ross' death and filled that post until the election of 1925.

Upton, Wyo., known originally as Irontown or Iron City, and later as Merino, began in 1890 as a Burlington Railroad depot near a set of sheep corrals. The town was not incorporated until 1909. The Burlington’s successor, the BNSF, remains an important employer today, as do the school district and a clinic operated by Weston County Health Services.

Verda James, a schoolteacher, deputy director of public instruction for the state of Wyoming, assistant superintendent of the Natrona County schools, and later a faculty member at Casper College, was first elected to the Wyoming House in 1954. She served eight terms. During the last term, 1969-1970, she was elected House speaker, the first woman to serve in that position for a full term.

Washakie County, formed in 1911 and named for the Shoshone Chief Washakie, continues to rely upon energy and agriculture as its main industries.

Fremont County, created in 1884 and named for famed explorer John C. Frémont, is still as diverse both economic factors and population as it was in the early days. Members of the Shoshone and Arapaho tribes continue to live and work on the Wind River Indian Reservation. Former reservation land north of Wind River was first opened to homesteaders in 1906. Ranching and irrigated farming have provided steadying influences over the decades to a local economy tied closely to booms and busts in gold, coal, uranium, iron-ore, oil and gas production.

Uinta County, one of the five counties of Wyoming Territory, was reduced to its present size in 1911. The Oregon, California, Mormon and Overland trails all passed through the county as well as the Union Pacific Railroad, the Lincoln Highway and Interstate 80. While the county is rich in natural resources like coal and oil and endures economic booms and busts as a result, agriculture continues to be a mainstay. Rancher John Myers established the first ranch on the Bear River drainage in 1858 and filed the first water right in what later became Wyoming Territory.

The Tongue River in northern Wyoming must have been as beautiful as it is now when George Bent saw it in 1865, with big, lazy curves under cottonwoods, the grass thickening on its banks and the trees sending out their first green shoots in early May. Nowadays, irrigated hay fields and the tiny towns of Dayton and Ranchester lie along the river. In May of 1865, however, one stretch of it was packed with human beings. That month, there was as large a town on the Tongue as that river has ever seen.

During Francis Warren's second term as Territorial Governor, Wyoming was granted statehood on July 10, 1890. Territorial Governor Warren was then elected Wyoming's first State Governor September 11, 1890.
