The Duamish Head begins as a long, shallow, sandy dive that progresses into eel grass beds, and then eventually to rack kelp before beginning a gradual slope to greater depths. The Duamish head gets very little dive traffic since the site lacks any real structure or large creatures, thus is a good spot to look for creatures unique to this type of environment. Sea pens and the nudibranchs that eat them, skates, dogfish and all sorts of flatfish are common sights here, plus all the small creatures that inhabit eel grass beds. It should be mentioned that the beginning of the drop-off is really quite far from shore and it is probably should not be attempted without a scooter or from a boat. Consider this site a shallow sand dive. If you desire depth then you can choose any of the nearby alki dive sites.
