Grindstone Island[edit | edit source]
Grindstone island is about seven miles long and three wide, and is the fourth largest island in the Thousand Islands. During the eighteenth century the island was heavily logged and cleared, mostly for agricultural use. Later stone quarries, shipyards, and a cheese factory making fine cheese were built on the island.
In the present day there are only ruins of the cheese factory as well as most of the farm buildings. There are year-round residents, a church, a cultural center, and a trail system.
