Come Join us on Saturday June 4th, 2016 8AM, at Haleiwa Ali'i Beach park to help clean up the reef and the Haleiwa Trench. Currently the Haleiwa trench, rumored to be a trench excivated by the Navy to hide submarines during WW2 is full of trash from the recently large winter swells. This trash is litering the floor of the trench and getting stuck in the healthy reef above it. Come help to pull trash out and make our dive sites and ocean more beautiful.
