Originally established as the Wyoming Insane Asylum by the Wyoming Territorial Legislature in 1886, the Wyoming State Hospital in Evanston opened in 1889 and operates today on the same site. The institution evolved and the campus was built according to trends in psychiatric thought and therapeutic practices. Notable among its superintendents was Dr. C.H. Solier, who ran the hospital from 1891 to 1930, and successfully deflected allegations of patient abuse in the 1920s.

Jim Geringer was first elected to the Wyoming Legislature in 1982, and served six years in each house before taking office as Governor of Wyoming in 1995.

John B. Kendrick rose from poverty to great wealth to the pinnacle of political power. He arrived in Wyoming Territory in 1879 with a Texas trail herd, and by the early 20th century was running his own ranches and a local bank. A Democrat, he was elected governor in 1914, and later served three terms in the U.S. Senate. There he worked tirelessly on irrigation, land use, and protection of natural resources. With humor, broad intelligence and a willingness to work with political opponents, he became a model for long-term success as a Democrat in a Republican state.

Grass was free and profits enormous in the cattle business in Wyoming Territory — for a while. The business dates to the 1850s, but the boom came after the Union Pacific Railroad connected Wyoming ranges to eastern markets. For a time it seemed as if every investor got rich. Finally, a weakening market and the overstocked range could not withstand two years of drought followed by a terrible winter. The big boom busted, following an economic pattern repeated many times since in an economy still based heavily on natural resources.

When Thomas Boylan started collecting dinosaur bones on his homestead in 1915, he first envisioned completing a dinosaur skeleton and using it to attract customers to his gas station on U. S. Highway 30 near Como Bluff. However, he was told that he didn’t have enough bones for that. Instead, he used more than 5,700 bones to build a structure that has become known worldwide as the Fossil Cabin. The historic Fossil Cabin was built in 1932 and stands about five miles east of Medicine Bow, Carbon County, Wyo. The cabin has been featured in Ripley’s Believe It or Not! and is listed on the National Register of Historic Places.

A late-1960s Atomic Energy Commission plan to extract Wyoming natural gas with five underground nuclear explosions won strong initial support from the oil and gas industry and the federal government. Finally, however, the idea stalled, thanks to the emergence of more information on possible dangers, to Washington politics, and especially to intense local opposition in Sublette County, Wyo., where the devices were slated to be detonated.

On Aug. 2, 1867, a large force of Oglala Sioux attacked woodcutters near Fort Phil Kearny. Soldiers assigned to protect the woodcutters took cover behind a ring of wagon boxes. After the intense battle, both sides claimed victory, and estimates of the dead and wounded varied widely.
