Ancient ice and powerful waves worked for eons to round the cobbles that grace Acadia’s beaches, and glaciers carried many of them great distances to this spot. Now the sea endlessly tumbles them with local rock, creating an ever-changing mosaic of colors and textures. Today these cobbles are part of a critical shoreline habitat, where small creatures hide from predators in the spaces between them and larvae cling to larger cobbles to keep from washing away when the tide goes out. These irreplaceable cobbles are an integral part of Acadia’s natural history and scenery, and they should be left in place.
