Wall, Large Rock Formation / Pinnacle
Coffin Rocks is a dive site just to the northwest end of deception Pass where it is slightly more protected from the local currents. It is a scenic location and an interesting dive site full of life.
The rocks barely break the surface during high tide. On the southwestern side of the rocks (facing Deception Island) a wall extends to about 60-70' and then continues to drop steeply. The bay side of the rocks is shallower and descends in a series of rocky shelves to the silty bay floor.
Beware of currents. They are unpredictable and not always consistent at this location, including strong upwelling and waterfall currents. Use a live boat. Swim into the bay for protection if necessary. The surface currents will often be stronger on the SW side of the rocks.
How to get there:
Coffin Rocks are located in the mouth of Bowman Bay on the west end of Deception Pass. They are a series of rocks located in the center of the bay's entrance still lying in the current swept portion of the channel. The rocks are almost covered during high tide, though never completely. Anchorage for boats and kayaks can be found on the north side of the rocks where it is shallower and better protected from waves and currents. It can be easily accesses by kayak from Bowman Bay.
This is a good alternative to Deception Pass if conditions are unfavorable. Other great nearby sites include Deception Island, Northwest Island, and Sares Head.
