In the fall of 1869, lawmakers in Wyoming’s first territorial legislature passed a bill allowing women the right to vote. The governor signed the bill into law Dec. 10, 1869, making the territory the first government in the world to grant full voting rights to women. The lawmakers mixed partisan politics, racial fears and an eye for national publicity in with a desire among some, at least, to do the right thing.

In March 1866, when whites and Indians together at Fort Laramie mourned the death of Mni Akuwin, daughter of Spotted Tail, chief of the Brulé Lakota, a colonel at the post hoped it was a sign of peace between the peoples. Peace hopes were shattered later that spring however, by the arrival of hundreds of troops to build forts on the Bozeman Trail, and two more years of bitter warfare followed. Finally in 1868, the tribes of the northern plains gathered at the fort and signed a treaty, ending the war—for a while.

John Richard’s bridge across the North Platte River near present Casper, Wyo. eased the way for thousands of those who traveled the Oregon, California and Mormon trails during the years 1852-1866. Because Richard spoke with a French accent, many people thought his name was Reshaw and began referring to the bridge as Reshaw’s Bridge. A number of diarists, including world traveler Sir Richard Burton, recorded their experiences and descriptions of the bridge and the mixed-race community that thrived at the nearby trading post.

Register Cliff, near present Guernsey, Wyo., is one of three large “registers of the desert” in Wyoming where Oregon-, California- and Utah-bound emigrants carved their names on rock. Many of the inscriptions are from the peak years of Oregon Trail travel in the 1840s and 1850s. The area close to Register Cliff was the first night’s camp west of Fort Laramie. Today, this site is a National Historic Site.

When the U.S. Army in 1866 sent troops to build a string of forts along the Bozeman Trail north from the North Platte River to the Montana gold fields, Lakota, Cheyenne and Arapaho tribes in that country reacted angrily. For two years, the tribes harassed and attacked the soldiers and travelers on the trail. After the Treaty of Fort Laramie in 1868, the Army withdrew, the Indians burnt the forts and for a few years, until hostilities started up again in the mid-1870s, the tribes the country largely to themselves.

The earliest people appear to have come to Wyoming from Asia about 11,000 years ago and archaeologists now think there’s a good chance the people were direct ancestors of Shoshone people who live in Wyoming now. In recent years, the mostly white archaeologists have realized it makes sense to ask Shoshone people for help understanding the pictures and carvings their ancestors left on the rocks.

The Piedmont Charcoal Kilns southwest of Evanston, Wyo. were built in 1869 to supply charcoal primarily to Utah mining and smelting operations. The town of Piedmont’s location—on the Union Pacific Railroad but near a ready timber supply in the Uinta Mountains—made it a logical spot for the industry. Most of the charcoal was shipped to the Salt Lake valley, and some to Fort Bridger for use in blacksmith forges and heating stoves. Piedmont was a railroad station on the Union Pacific line. Three of the original five kilns remain standing. The site is on the National Register of Historic Places.

As the beaver trade waned in the 1830s, so did economic reasons for an American toehold in the Oregon country, still under joint British-American occupancy. Religion shifted the balance of power, however, when American Protestant missionaries crossed the Rocky Mountains with an eye toward converting the tribes of the Northwest. Soon these men brought their wives with them as well. In 1836, Narcissa Whitman and Eliza Spalding were the first Euro-American women to cross South Pass, and these people became the vanguard of American settlement of Oregon.

Pinedale, Wyo. was founded in 1904, incorporated in 1912 and became seat of brand-new Sublette County in western Wyoming in 1921, when the town still boasted only about 100 people. Despite its isolation, the town survived well through the 20th century on ranching and tourism. It began to change more quickly in the early 1990s, as development sped up in the nearby Pinedale Anticline and Jonah natural gas fields. Today, with more than 2,000 people, the town works hard to keep its traditions while dealing with steady, industrial growth.

One of Wyoming’s early large-scale irrigation projects dates to the 1880s in what’s now Platte County, Wyoming and the county, organized in early 1913, still is perhaps best known for its reservoirs and recreation areas. The Oregon Trail ruts and Register Cliff near Guernsey serve as reminders of the pioneer heritage of the area and a coal-fired power plant near Wheatland provides jobs and economic stability.
