Where is Pine Hawk? Pine Hawk is in South Acton, MA along the Assabet River.
For generations, children in South Acton have been discovering arrowheads and spear points in their backyards. When digging began for the new waste water treatment project in 1999, we discovered why. Archaeologists made an amazing discovery. They found evidence that proves that people were living here in Acton 7,000 years ago along the Assabet River!
