North Platte River: Gateway Corridor
Currents of History Travel Alongside the North Platte River
Routes along the river originally used by Native Americans were later adopted by fur traders. Beginning as a trickle, waves of wagon train emigrants turned the North Platte River Valley into a major corridor west. Permanent communities came later, and were dependent on the transportation routes that continued to follow the river. The wagon roads, railroads, and eventually a paved highway made settlement possible, contributing to the growth of the North Platte River Valley.

Native Americans: the First Miners
Wyoming’s first inhabitants arrived in this area of Wyoming, known as the Hartville Uplift, approximately 13,500 years ago. They found a variety of food resources and high quality stone for tool making and red ocher pigment.

For thousands of years, Native Americans quarried stone from the famous Spanish Diggings for use in making arrowheads, spear points, scrapers, awls, and other tools. The first Euro-American explorers thought the Spanish developed the quarries in their search for gold, which resulted in the site’s name.

Historic Trails Provide the Path for New Lives
By the mid-1840s, emigrants from all over the world flowed through the North Platte River Valley in search of better lives in the west. Known popularly today as the Oregon Trail, the great overland emigration route laid the path for the Mormons to the Great Salt Lake Valley, for farmers to Oregon’s Willamette Valley, for gold seekers to California, and settlers to many places in-between.

From 1860 through 1861, the Pony Express riders carried their mail along the same trail.

The discovery of gold in the Black Hills of South Dakota in 1874 led to the establishment of the north/south Cheyenne-Deadwood Stage Route.

Railroads Spur Industry
The railroad linked communities and provided the necessary transport of goods, making it possible for local industries to survive. Railroads carried cattle, sheep, iron, and coal to markets.

By 1887, the Cheyenne and Northern Railway reached Hartville Junction near Guernsey.

In 1913, the Chicago, Burlington and Quincy entered Guernsey, eventually becoming the Burlington Northern Santa Fe Railway seen today.

1. Sunrise, Wyoming - Wyoming Tales and Trail. Sunrise is a company town in the fullest sense. Everthing, and may it be said everybody, is owned by the Colorado Fuel and Iron Company. No special brand is necessary, for the fact impresses itself indelibly on all who come here. Visitors are not especially welcomed, which a glance at the passenger accommodations on the train that meets the Colorado & Southern at Hartville Junction forces itself on all comers.
