Yreka Gap-filler Radar Site (CA, USA)

At the top of Gunsight Peak sits a former US Air Force Gap-filler radar site. It was active in the late 50s and early 60s. The classic "L" shaped building is still in use supporting a microwave relay station. The footings for the radar tower are still present.
This was SAGE site Z-180A.
The radar was a FPS-18 search.
