Very interesting report on the salt marsh where the Bunker land and cemetery is located. The expected rise in sea level is likely to flood the Bunker cemetery eventually. A good reason everyone in our family ought to be working against climate change as much as possible. http://www.wildlife.state.nh.us/nongame/documents/appendixb-saltmarsh.pdf Oyster River is a tributary of the Piscataqua River and got its name from all its oyster beds that no longer exist. The Bunker Garrison house was located on Oyster River.
