Carried the boat to the cottage last week so I don't have my GPS. The ASPHALT pile is located south of the Green Boey #1 just outside the GREAT WICOMICO river. I have some GPS reading that will get you close. 37' 45 00W 76' 14 00N From here you can see the Yellow Boey marking the ASPHALT PILE. Boey is identical to the one at NNReef.
