Tar Island

Tar Island is a river island in the Thousand Islands archipelago situated in the St. Lawrence River. The island supports mixed forest and open shoreline areas that provide habitat for various bird species.

The island witnessed a British-American confrontation during the War of 1812. A significant naval vessel was captured in the area, marking a strategic moment in regional maritime history.

Archaeological findings on Tar Island include Iroquois arrowheads, bones, and red ochre painted stars, indicating early Native American settlement in the area.

The island can be viewed from boat tours that travel through the Thousand Islands. Visitors should note that this area experiences significant vessel traffic and the best views are from the water at a distance.

Black tourmaline deposits exist southeast of the island, combined with white quartz, cream-colored feldspar, and green-yellow mica formations.
