Located on Pendleton Hill Road (Rt.49) 1.4 miles north of Grindstone Hill Road, (or .4 miles south of the Dirlam Preserve if you are coming from Voluntown). Pendleton Hill Brook takes its journey south through this small preserve. The riparian buffers benefit the wildlife and keep the brook clean and cold. It also is a nice buffer for the Thompson cemetery. Received as a P&Z/developer’s set-aside in 1995.
