I call this Alki south and it is an old sewer pipe that has rocks and growth on it going way out into 35' of water. It is at the Charles Richey Sr. viewpoint. Lots of small perch everywhere. Large stars and anemones. Lots of painted greenling. It is out from the intersections of Beach Drive SW, 63rd and also Spokane street comes in there. Nice beach. Take a compass heading while following the pipe out (about 200 degrees magnetic?). You will not see rocks or pipe at between 20 and 25 feet, keep going the best is yet to come. Peek back inside the end of the pipe but I don't think it is safe to swim inside the pipe (6' diameter?). A few more rocks and debris south of the end of the pipe in 38 feet of water. (I dove with a tide of 6.3 feet, so these depths are relative to that.) Weight so you can spend some time in shallow water (10-15')looking around all the rocks when you come back in.
