Granite from Cape Ann

Cape Ann hosts many Granite deposits. As a result the town of Rockport Massachusetts hosted many immigrants from Scandinavia with a tradition in Quarrying, although neighboring Gloucester maintained it's mainly Italian and Portuguese population due to being a major fishing port. Granite was shipped throughout New England and beyond, however the end of the 19th Century saw cheaper alternatives to Granite and the industry slowly died, resulting in multiple artificial lakes across Rockport and Gloucester. The main usage of Cape Ann Granite was not for countertops but for construction projects both for foundations and roads.

Granite and other quarried rocks are separated with multiple "feathers" and wedges" that are struck down by hand with hammers until a rectangular block is made

The town of Rockport used this Granite to build multiple breakwaters, supposedly with the purpose of building a future Naval base but halted the construction during World War 2, leaving several unfished projects by the sea.

The Initial plan called for an extensive Break water off the coast of Rockport Harbor, but never came to fruition.
