Yes turns out it wasn’t THAT big a mystery or that hard to get to. Heck I have a friend who drove there today.
Someone knew enough to know the public could check the flight plan of the survey; which was some special knowledge a few might have and the news article got enough people working on it so with that info they found it pretty fast.
There’s a sub-group over on reddit with over 400 members devoted to finding it.
There’s now a petition going round to keep the thing intact and in place.
It’s going to become a destination the way things are going.

Anyone nearby (relatively) wants to go pm me
