Morrocco,
Take MD Rt. 4 south towards Solomons Island. Stop at the bridge crosing the Pax. River. You can launch a boat right under the Bridge there. Make a left turn and follow the river until it empties into the bay. The reef is on your right, off the coast of the military base (airforce?)approximately 500 yards out. At one time it was marked with 2 orange markersindicating the lenth of the reef. But that was years ago. I haven't fish there in a while now, so I can't tell you if its still marked.
