Anyone who lives in earthquake country knows this isn't true. The energy
in an earthquake is sound.
Also, there is an entire seismic industry based on the fact that soil is a
good conductor of sound.
The primary conduction is probably through rock, not the soil on top of
it. Also earthquakes and even seismic sounders are pretty "loud" to
being with.
To solve the original problem, how about drilling a core every few feet
along the path? Commonly used when siting buildings to figure out what
they are going to be built on/if they'd have to blast bedrock to finish
the excavation.
Get a piece of tube, maybe 6' long, and connect high-pressure water to
one end of it, and use the other to shove through the loose gravel until
you hit something big.
Good Luck!
