Coal and the railroad shaped the towns of the Yampa Valley
Routt County's towns grew up around ranching, coal, and the arrival of the railroad, which helped shift the county's center to the Yampa Valley and Steamboat Springs.

If you look at a map of Routt County and wonder why the towns sit where they do, the answer is mostly water, ranching, coal, and the railroad.
Settlers came to ranch and farm the fertile valleys of the Yampa River, and cattle became a backbone of the local economy. At the same time, large coal deposits were found in the western part of the county and around Oak Creek, which grew up as a coal-mining town. Hayden took shape as a ranching and farming community along the river and rail line, and Steamboat Springs grew around its hot springs.
The railroad changed the balance. Once rail reached the valley in the early 1900s, coal, cattle, and farm goods could finally ship out to the rest of the state. With that connection, growth and county functions shifted toward the Yampa Valley and Steamboat Springs.
You can still read this history in the landscape: ranchland in the open valleys, old coal country to the south and west, and a county seat built around its springs. It is a working past, not a theme-park one.
