Third House Nature Center, Inc. invites you to join our Anniversary Celebration of:

  • The 50th anniversary of the first purchase of land by Suffolk County which led to the formation of the 1,183-acre Montauk County Park and the preservation of the Indian Field Site.

  • The 50th anniversary of the designation of Big Reed Pond as a “National Natural Landmark”.

  • The 30th anniversary of the founding of Third House Nature Center, Inc.


The 1183-acre Montauk County Park was the last Montaukett tribal land remaining in the Town of East Hampton until the ruling in 1885 that dispossessed the tribe of these lands. When it became part of the Suffolk County Parks System the land was preserved from development.The Park is unique for its diverse ecological history and for the Montaukett archeological sites.


Third House Nature Center works in cooperation with Suffolk County Parks to preserve and maintain these important sites for environmental, educational, cultural, and historic purposes.
