The Paint Mine Conservation Area, near the Estabrook School playing fields off Grove Street, is comprised of about 46…More acres of land, including Hennessey's Field, and is the habitat for a range of animals and birds. The area was named for a 19th century ochre mine that historically provided pigment for paint, and is still visible today. A series of small ponds created for muskrat trapping were abandoned in the 1950s, and have reverted to bog-like areas. The Simonds Brook conservation area is also nearby, on the other side of Grove Street.
Access trails run in from Grove Street, Turning Mill Road, the Estabrook School parking area and Robinson Road.
