You are standing on a large grout pile, a mountain of waste granite pieces dumped here over a period of many years. If you walk to the end of the pile, face the ocean and look to your right toward the horizon, you will see a small part of the proposed Sandy Bay Breakwater. In 1885, construction of the breakwater began off the coast of Rockport to provide a safe haven midway between Boston and Portland for sailing ships. Lack of continued federal funding and the decline of sailing ships brought the project to a halt in 1915. Much of the granite from the Babson Farm Quarry went into building the breakwater which is now considered a hazard to navigation.
