Also posted on r/HighStrangeness, but I thought some of you might be more motivated.
Stupid giant UFO discussions and another post that discussed Google Earth timeline images led me to browsing at the surface geology around the Pine Gap facility. I came across this other facility which looks a little odd, and I can’t find much info on it. Google only goes back to the mid 80’s and both sites are there then, but it does show the extra buildings going down in 2019. Coords are 23d 31’25.05″S, 133d 40’49.15″E. There are a few weird things going on, and it doesn’t look like mining of regular surface mineral sampling. Can anyone with better detective skills than me work out what it is?
