Pawtuckaway State Park is located in Nottingham New Hampshire. There are several trails to take in this 5000 acre preserve, one being Boulder Trail. If one takes a look at the satellite image of Pawtuckaway’ s Mountain range, you can see a circular formation called a ring dyke made by an ancient volcano about 130 million years ago. During the Ice Age, approximately 18,000 years ago, a mile high ice sheet sat on top of this area and moved these gigantic rocks as it melted, known as glacial erratics. Now we have boulders resting amongst trees in a beautiful forest for people to climb and admire.
