Denver, the governor of the Kansas Territory, and the city's founders hoped that he would help promote their new settlement. However, Governor Denver never actually visited the city.
Colorado random facts
La Plata County, located in southwestern Colorado, has a rich and diverse history dating back thousands of years. The region was originally home to Native American tribes such as the Ancestral Puebloans and Ute people, who lived off the land and developed agricultural practices. European explorers, including Juan Maria de Rivera and Juan Maria Antonio Rivera, were some of the first non-native visitors to the area in the late 18th century.

In the mid-19th century, the discovery of gold and silver in the nearby San Juan Mountains attracted a wave of prospectors to La Plata County. This led to the establishment of mining camps and towns like Silverton and Durango, which quickly became centers of trade and commerce. The Denver and Rio Grande Western Railroad reached Durango in the 1880s, connecting the area to the rest of the country and further fueling economic growth.

Durango, the county seat and largest city in La Plata County, thrived as a hub for mining, logging, and agriculture. The town saw significant developments in education and infrastructure, including the establishment of Fort Lewis College in 1911, which played a crucial role in the region's educational and cultural growth.

In recent decades, La Plata County has become a popular tourist destination, drawing visitors with its stunning natural beauty, outdoor recreational activities, and historic sites.

Today, La Plata County continues to honor its history while embracing a forward-looking approach to development and sustainability.
