Highly exposed locations are unlikely to contain undisturbed sites or sedimentary deposits The slow rate of sea-level rise provided time to accumulate Coastal/estuarine in the Gulf of Maine, as well as the erosion of glacial landforms. Sedimentary deposits between15-25 m depth representing formations between 7-11ka may be preserved because of the slow rate of local sea-level rise In Bass Harbor, human occupation occurred in a shoreline setting involving erosion of a moraine and formation of spits and wetlands near a brackish-water basin between 9 ka and 8 ka. 28.
