The Erie Triangle is often described as a "tab" attached to the Keystone State. The water off the coast of the Erie Triangle is known as the Graveyard of Lake Erie due to the large number of shipwrecks that occurred in the area's stormy waters in the 18th and 19th centuries. It was also the site of a preliminary battle between forces that participated in the Battle of Lake Erie during the War of 1812. The battle itself took place in the Lake Erie Islands, at the western end of the lake.
