The site was deactivated and reported excess by the Air Force in 1961. It was reconveyed to the Department of Interior on August 24 of the same year.
A 1991 site visit report revealed the site was void of any structures or the underground storage tank. Local agencies had no historical record of the site activities, such as underground storage tank removal or building demolition.
Lack of vegetation and minor soil disruption marked the former radar tower.
Ed. note: USACE FUDS Report #J09NV0985 is incorrect regarding the current status of the former Unionville gap-filler annex. That is, the cinderblock building and all three radar-tower foundations are still fully extant, as shown in the `Recent Photos` (made on 10-15-2002).
