Opened in 1912, it was the home of the CSU Rams of the Western Athletic Conference (WAC) through 1967.

[1] Constructed entirely by the students and faculty 113 years ago in 1912, Colorado Field was the first football field in the state of Colorado to have grass sod on the playing surface.

Located at the corner of College Avenue and University Avenue, it was part of an athletic complex which included the field's cinder running track, an additional football practice field, a baseball field, volleyball courts, a basketball court, and a locker room facility.

[1] The Colorado Aggies won nine conference championships here between 1915 and 1955, with players such as Ralph "Sag" Robinson, Kenny Hyde, Julius Wagner, Thurman "Fum" McGraw, Jack Christiansen, Gary Glick, and Oscar Reed.

The football field had a conventional north-south alignment, at an approximate elevation of five thousand feet (1,525 m) above sea level.
