    My napkin math says around 1000 meters. If the rock falls for 14-15 seconds and takes 3 seconds to echo up the chamber that’s about 1000 meters either way terminal velocity and speed of sound.

      Nerdier math puts the 14 second total time as 12s falling and 2s sound returning, for a depth of 700m. Your napkin was fairly close!

      Thank you!

      Edit: the other acceptable answer is “deep af.” But I appreciate that you took it seriously and shared.
