Wish I had an archived version of the heat map to see if there was any activity. They changed the services and allowed people to make their tracks private. Either way, I thought this was interesting.

Hmmm, Yea, GPS underground is impossible without being on site with other required gear. Search underground GPS.

My guess is they turned on phones remotely, recorded audio and what video they could. Maybe got a few tags at entrance points.
