Mehgan Heaney-Grier, who lives near Boulder,  set the first ever US freedive record for both men and women by diving unassisted, to a depth of 155 ft on a single breath of air.  Less than a year later she beat her own record with a successful dive to 165 ft.  The master diver is also a mother, fashion model/actor/stunt-diver, and marine biologist!  And now you can see her on the Discovery Channel’s new series, “Treasure Quest: Snake Island” that is taking treasure hunting to dangerous new depths. It premieres Friday, July 17th!
