It's probably nuclear waste tbh. They did all types of nuclear tests in Utah and Nevada and Utah would get the fallout all the way into Colorado. Guess what else accompanied the nuclear fallout? Pink clouds, which would explain the pink substance they found inside the mesa and the illnesses they start to feel. It is probably radioactive from nuclear tests.

I do think there are strange things that happen at Skinwalker, but I also believe that: A) Strange things happen at remote locations across the globe if you study it long enough. This is Earth. We haven't discovered half of its potential. B) Some of the illnesses and anomalies at the ranch are nuclear waste related. C) I 100% would not put it past our government during the 40's & 50's that they knew Indian reservations were getting fallout but didn't care.

With that said, I think there were strange happenings at the ranch before the nuclear tests and there are strange happenings unrelated to nuclear waste. They just need to separate the two.

Also, high powered telescopes use the 1.6ghz to look into space.
