I may have discovered something.
About 700m up from the site. I was listening to the sounds it makes when your near it. And from what i hear. there is some form of chittering, chirping, clicking whatever it sounds like to you.

Im not sure what it is. So i slowed it down.

What do you guys think?
Look, i don't want to be the guy who always hears morse everywhere, but it does sound a lot like morse.
I'm unable to figure out exactly how many clicks are there but if this is morse it can be one of those 4 depending on the amount of symbols
1. .... .-.. = HL
2. .... .-... = H<AS>
3. ... .-... = S<AS>
4. ... .-.. = SL
However since there are only 2-3 letters in this i think this is just a dead end, unless of course, there is some crazy meta reference here that i'm simply not seeing.
