Stone Chambers are found in the North Eastern section of the United States.   Their purpose is still unclear, although many theories exist.  Dating is difficult and their culture is unknown.  

A common theory is that they are root cellars, perhaps some were used that way by colonists but an ideal environment to store food would be a dry area. The area within the chambers are damp and not nearly large enough for long term food storage to survive a New England Winter.  Several are astronomically aligned with the door opening directed toward the South East, but not all of them. Their purpose is currently unknown, but great care went in to building each structure.

Thousands of miles of stone walls and stone chambers cover the land of New England.  They are found along roads, highways, and in State and National Parks.  These mysterious structures are hidden in plain site.  Who built them?  When? and Why?  So many questions surround these enigmatic structures that it is imperative these structures be preserved for future generations.

 The complex construction is similar to neolithic stone structures found in Ireland, Scotland, England, and France.  The chambers are built with a corbelled roof and a cap stone above the entrance.  Many stones used weigh several tons.  It seems likely the stone structures in all of these areas share a common culture, suggesting there is an ancient maritime culture that crossed the Atlantic Ocean.  Other evidence also suggests this possibility, one example is a similarity between the  Solutrean point found in France and the North American Clovis point.

Dating the chambers is tricky because they are stone.  An analysis completed by the U.S. Geological Survey dated samples of backfill taken from the entrance of the Upton Chamber in Massachusetts to 1350 AD- 1625 AD. (NEARA Transit Volume 28, No. 1)  In New Hampshire, America's Stonehenge has been carbon dated to at least 2000 B.C.  When Early colonists arrived the stone walls and chambers were already here.  In 1654  John Pynchon (the founder of Springfield, Massachusetts)  wrote  a letter describing a newly discovered stone wall and fort in Groton, CT now known as Gungywamp.  This letter suggests that the colonists did not build the structures.
