Hummers, Those Strange Sounds

Sounds like you both believe there was some form a tunnelling going on under your feet.
That is a very real possibility.
Could the sounds be form caves being created or collapsing like this cave here in the article and video.

I understand that our Earth has these large crystal caves everywhere.

I don't think it was tunneling in my case. There aren't even basements or storm cellars down there because it was only 25-30 miles as the crow flies to the Gulf of Mexico and basically a swamp between two rivers situated AT sea level.  I guess it could be possible but not plausible.
