Crab Island - September 1, 2018
Crab Island is a roughly 40-acre (0.16 km2) limestone island situated in Lake Champlain just outside Plattsburgh Bay in the town of Plattsburgh in Clinton County in upstate New York. During the War of 1812, the island was utilized as a military field hospital for convalescent soldiers as well as both British and American casualties of the Battle of Plattsburgh. The island is the site of a mass grave believed to contain the remains of roughly 150 of those casualties.
Crab Island is infamous locally for its poison ivy, which grows abundantly on the island. Its name is thought to come from the large amounts of "crabs" (referring to fossilized shells, trilobites, and other fossils) found along the island's limestone shoreline - Source Wikipedia
