About Jefferson County
Jefferson County Timeline
Jefferson County, Colorado, is located in the central part of the state and has a rich history that dates back thousands of years. The area was first inhabited by Native American tribes, including the Ute and Arapaho, who lived off the land and utilized the region's natural resources.
In the early 1800s, European and American settlers started to arrive in the area, attracted by its fertile lands and abundant wildlife. Charles Hagerman built the first permanent structure in the county in 1859, establishing a small farming community. The discovery of gold in the nearby Colorado mountains soon brought a rush of miners to the area, leading to the establishment of mining camps and towns.
Jefferson County witnessed significant growth in the late 19th century with the construction of railroads, which connected the region to the rest of the country. The Colorado Central Railroad, completed in 1878, contributed to the development of several towns within the county, including Golden and Arvada. These towns became centers of commerce and attracted businesses, schools, and other essential services.
The 20th century saw Jefferson County transform from a predominantly agricultural and mining economy to a more diverse and urbanized area. The construction of major highways, such as Interstate 70, spurred suburbanization and further economic growth. The county experienced a population boom, fueled by the growth of nearby Denver.
Today, Jefferson County encompasses a mix of urban and rural areas, offering residents a high quality of life with access to natural attractions like the Rocky Mountains and numerous parks. The county continues to attract new businesses and residents while preserving its rich history and natural beauty.
