Recent Photos of Yaak AFS, MT
-----------------------------------------------------------------------------------------------------------------------------------------------------------------
The following photos were taken by Tom Page on 19 June 2018. All photos were taken at the top of Hensley Hill where the AC&W Radar Site / Operations area was located. Nothing remains down below at the cantonment area and the housing area except for mostly-empty fields. Little remains at the top as well --- just a few foundations and the roads. The first image below shows side-by-side aerial images of the radar site in 1954 and in 2014; the numbers correspond to the photos, as indicated.
Location #1 was the AN/FPS-3 search radar arctic tower location (the radome in the 1954 image is fairly clear). Location #2 is unknown, but might have been the Materiel Control building. Location #3 appears to have been the AC&W Operations building, with possibly the diesel Power Plant building next to it. Location #4 is unknown. Location #5 appears to have been one of the manual Ground/Air/Ground (G/A/G) Radio buildings, maybe the Radio Receiver site. Location #6 appears to have been where one of the steel temperate height-finder radar towers stood, either the AN/FPS-4 or the AN/FPS-6. Location #7 appears to have been where the other manual G/A/G Radio building stood, maybe the Radio Transmitter site. Finally, the 'x' denotes the spot where the road to the second Radio site branches off from the main access road. Comments and corrections are welcome.

Location #1: A view of where the AN/FPS-3 search radar tower apparently once stood (looking north)

Location #1: Another view of where the search radar tower apparently once stood, plus the top of the site road (looking north-northeast)
.
Location #1: One more view of where the search radar tower apparently once stood. A cluster of four bolts protrude from the ground near the right center; possibly those bolts were part of the antenna support in the tower's center? See next photo for a close-up. (looking south)
