Yes, I'm pretty sure this is not the first time this has happened, I recall something last year about this too, or it might have been 2013.
And the second video about people in protective gear... this is an active site of special scientific importance, they regularly conduct research
there, it's part of the park and it's not a big suspicious secret. There are documents about this too, with a full statement about them conducting
GPR (Ground Penetrating Radar) to map the areas beneath ground level, in places of special scientific interest.
There is nothing strange or suspicious about any of this as far as I can see.
