We are well underway here in Maine, mapping the Seal Cove wreck. Placing a non-intrusive baseline proved problematic, but we were lucky to have two large boulders nearby to tie into. Since the wreck is in the intertidal zone, we can only work when the tide lets us. Each day has seen two shifts of mapping and numerous volunteers, from Acadia National Park staff to members of the local community. We have both east and west sides of the vessel mapped from zero to 38 feet. So far the most intriguing feature is the use of treenails, or wooden pegs, to hold the outer hull planking to the frames.
