Air Defense Command Patch
LaMotte Gap-Filler Annex, Air Defense Radar Station GFA-Z-81B
On May 28, 1958 the Air Force acquired 0.67 acres. The Air Force constructed and operated the site until August 1968. The site consisted of a 20'x40' and 20'x20' masonry building and 78' radar tower, chain link fence, gravel drive and sidewalk, and underground storage tank.
The site was declared excess and quitclaimed April 8, 1970 to private owners.
The cache is located just east of the site, which is now a private residence. You can still see the main building and chain link fence. The radar tower was removed years ago.
