This is a stitched imaged made from two captures with the Rodenstock 70mm/5.6 HR-Digaron-W lens, Phase One IQ4-150 digital back (@ ISO 50), and a Cambo WRS 1250 camera, shifted left/right 15mm, producing a 230MP final image.
The full resolution (16152x14043) version is finally up on Flickr. There had been a bug preventing the upload of very large images there, which had forced me to use a large (but reduced size, 100MP) version as a placeholder there.
From 1958 through 1980, this incongruous four story (82 foot) monolith was the centerpiece of the "Almaden Air Force Station", a long-range radar site that was part of NORAD's SAGE early warning system. The blast-hardened concrete building served as the platform for an FPS-24 radar system, a massive 120 foot wide reflector that emitted a 5 megawatt VHF pulse, continuously rotating at 5 RPM.
Notoriously, the signal disrupted TV and radio reception throughout the San Jose area.
