A Little History

The Army Air Forces and the US Air Force used the Siskiyou County airport over two separate periods from 1942 to 1945 and from 1962 to 1972.  The site first served as an auxiliary field and later as a dispersal site.

The airport was constructed with funds from the Civil Aeronautics Administration.  The Army upgraded and extended the original runways to hangle bombardment aircraft, as well as adding taxiways, a night lighting systems, a power control building and enclosed the field with a barbed wire fence.  In the fall of 1943 the airfield was a sub-base of Hamiliton Field (present day Novato, CA).  In May 1944, Army Air Forces reassigned the airfield to Chico Army Airfield and it remain an unmanned auxiliary field and primarily functioned as an emergency landing field for disabled aircraft.  In November of 1944 the Interdepartmental Air Traffic Control Board approved used of the field by Siskiyou County as an alternate airport for commercial scheduled air carrier operations.

On September 13, 1962 US Air Force Air Defense Command leased the airport for use as a dispersal site.  By December 1964, the Air Force began improvements to the site and in May 1972 terminated the lease with the County.

Today the Siskiyou County airport is used primarly for general aviation.
