Carleton Place resident Jill Heinerth has charted some of the world’s biggest underwater caves in Florida and Mexico. She has dived into the far reaches of Egyptian and Libyan deserts. And if you thought those were bold expeditions, Jill got to explore underwater caves that cut into the bottom of the world’s largest-known iceberg. Most recently, she has explored the Ottawa River’s cave system, while also completing a new book that details her life as a cave diver. Heinerth joins Andrew Pinsent on CFRA Live.
