Here are two of a series of audio interviews I recorded with Jason Mallinson. Hope you enjoy them.
The first is on the 2013 San Agustin Expedition in Mexico, in which he and Chris Jewell dived the final sump in Huautla.
The second is on Jason's continued exploration in Pozo Azul, with a description of a very close call in 2016. Scary listening!!
Many thanks to Mike Stace for helping to clean up the audio files.
