Colorado State University is one of our nation's leading research universities with world-class research in infectious disease, atmospheric science, clean energy technologies, and environmental science. It was founded in 1870 as the Colorado Agricultural College, six years before the Colorado Territory became a state. Colorado State University, located in Fort Collins, Colorado, is situated on nearly 5,000 acres of land, including the main campus, a foothills campus, an agricultural campus, and a mountain campus (Pingree Park). Colorado State also has 4,600 acres for research centers, Cooperative Extension offices, and Colorado State Forest Service stations. |
