Cape Ann was formed in a great and lovely mishap. The black speckled white rock that covers, shapes and defines the cape, that even today stands immovable in backyards breaking up sidewalks, determining the paths of streets is an unusually dense and hard variety of granite. The density is characteristic of granite normally found deep in the earth. When the glaciers started moving south they carried with them rock churned up from below the surface. Off the coast of Massachusetts, the ice hit a crevice caused by a fault line and hung-up there, started to melt and deposited large amounts of rock.
Cape Ann was formed.
