We talk to International Divers Hall of Fame member, cave diver, photographer, writer and speaker Jill Heinerth. We hear how this intrepid explorer became one of the first ever to dive inside an Antarctic iceberg, and how she almost didn’t live to tell the tale. We also how her passion for exploration has led to Jill discovering secrets of the ancient Mayan civilisation that could influence a better future for our planet and the people on it.
