The southwest tip of the island is very shallow (15-20 ft) and is covered with boulders for several hundred yards where a large variety of small marine life and endless rock crab can be found. A great spot for snorkeling. The west side of the island has a gradual slope with an endless bed of sea lettuce and Dungeness crab. The east side is slightly steeper and is home to eel grass beds. The large variety of substrate around this island makes it an entertaining dive site with potential to see a wide variety of sea life. There is fantastic clamming for Hose and Geoduck on the west side and the season is usually open much longer than Kopachuck.
