History

Prior to Wyoming's settlement by European-based populations, the area's stretches played host to nomadic tribes such as Cheyenne, Arapaho, Shoshone, and Sioux.

New York investor John Jacob Astor established the settlement of Astoria on the Columbia River, and sent Robert Stuart eastward to blaze a trail and lay the foundation of a string of trading posts. Stuart documented the South Pass Route through the Continental Divide, near the SW corner of present-day Natrona County. Stuart's company erected the first hut in the area in 1812, near present-day Bessemer Bend.

In 1840, Father Pierre-Jean De Smet began preaching the Christian teaching to this area's indigenous peoples. He carved his name on Independence Rock and called it The Register of the Desert. Later explorers who inscribed the rock include John C. Frémont (1843), who explored the country along the Platte and Sweetwater Rivers. ^[4]

The first Euro-American settlement occurred in the Casper area in the late 19th century. ^[5] Natrona County was created by the legislature of the Wyoming Territory on March 9, 1888, and it was organized in 1890. ^[6] The land for Natrona County was annexed from Carbon County.

Natrona County was named for the deposits of natron found in the area. ^[7] According to George Mitchell, first mayor of Casper and member of the organization commission for Natrona County, the name was first suggested "by my old friend the late Cy Iba, who at one time owned the soda lakes." ^[8] In 1909, Natrona County gained land from Fremont County. The boundaries were adjusted slightly in 1911 and 1931, and at that point the county gained its present outline.

Politics

Like almost all of Wyoming, Natrona is a heavily Republican county. It is rather conservative for an urban county, having gone Republican in all but three elections since 1944. No Democratic presidential candidate has won forty percent of the county's vote since Lyndon Johnson garnered 52 percent in his 1964 landslide against Barry Goldwater. Bill Clinton did win a 100-vote plurality in the 1992 election due to a significant third-party vote. In 2020, Donald Trump received 71.8% of the vote, the county's highest vote percentage for any presidential candidate since Wyoming statehood in 1890. ^[20]
