Mohegan Quarry, Sylvan Glen Preserve, Yorktown. The quarry works in Sylvan Glen were abandoned rather abruptly, leaving behind a fascinating and unusually vivid reminder of our community’s history. Walk amongst the remnants, strewn with old machinery and half-dressed stones—some of them destined for famous landmarks. Meet at the Sylvan Glen/Morris Lane entrance. From Lexington Avenue take Morris Lane until it dead-ends at the parking lot.
