Cashes Ledge, an underwater mountain range 80 miles off the coast of Cape Ann, Massachusetts, is difficult to get to and even harder to dive, but when you do, it’s worth it. Boasting the largest coldwater kelp forest along the Atlantic seaboard, Cashes Ledge is a biodiversity hotspot and a safe haven for rare and unique species. As such, Conservation Law Foundation is presently engaged in a campaign to designate Cashes Ledge as a Marine National Monument. Dive in with us as we share stunning film footage from a recent expedition as well as findings from new scientific research, and see for yourself why this place is worth protecting.
