History

The site of Aspen/Pitkin County Airport was first occupied by settlers in 1881, with the establishment of the Stapleton ranch, a 320-acre (130 ha) homestead. The first building on the site, a log cabin, sat on the east side of the present-day runway. The Stapleton family grew potatoes and raised animals, including sheep, cattle, and hogs.

A private gravel airstrip opened on the Stapleton ranch in 1946, promoted by Walter Paepcke and John Spachner. The airstrip was open to the public, but was mostly used by the aviation department of the Aspen Institute, the precursor of Aspen Airways.

The Pitkin County government gained control of the gravel airstrip in the 1956, and began a project to pave the runway. County commissioner Tom Sardy headed the project, and the airport was renamed Sardy Field in his honor in 1958.

The original paved runway was 5,000 by 50 feet (1,524 by 15 m). The runway has been expanded four times since, reaching its current dimensions in 2011.
