Point Whitney
A life-encrusted intake pipe extends out, running north-south. You'll find the pipe starting at about 15' and running down to 100 feet, more or less depending on the tides. Look for GPOs under the supports. The start of the pipe is located near the center of the parking area. (There's really two pipes, but one is shorter.) Octopus Gardens Dive Shop has a good map and write-up of this site on. Point Whitney (near the Washington State Shellfish Laboratory) is a fine site on the Hood Canal north of Hoodsport.
