Made with Xara Web Designer 1954-2009 Rocky Mountain Modeleers Clifton Field is our small field with an asphalt runway measuring 100' x 20'. It is located on the South-East corner of North College Ave. and Conifer St. in Fort Collins. Larger planes may find the field a bit cramped, but small electric planes and helicopters are right at home here. Turn into Jax's eastern most parking lot. (This may be a right or left depending on which direction you're heading on Conifer St.) Proceed to a small dirt road on the south end of Jax's parking lot. This road should take you right to the field. Directions
