A geophone, or a hydrophone can do that without drilling. Sound carries
well underground. Just bury your hydrophone with a shovel to dig a small
hole. Or even just drop it in a small pool of water and it will pick up
the surrounding soil sounds. I have problems when recording frogs with
my hydrophone of noise pollution from nearby wells and such like.

Or Gordon could have done it in a cave with a regular mic, though I
don't know that recording to know.
