Bolton Notch State Park
Bolton Notch State Park has a wonderfully maintained State hiking trail that makes its way through the park. The trail is part of an old railroad bed that is adjacent to unused power lines, which once provided electricity to the railroad . The trail is very flat and wide, providing an excellent place to walk or ride a bike. The rocks at Bolton Notch State Park tell us that the area was once the site of an ancient transgressing sea, part of which can be observed along the old railroad.
Another interesting feature at Bolton Notch State Park is located at the very top of the "notch". At the top of the cliff, in the marble exposure, there are several caves large enough to accommodate a human. Calcite is the predominate mineral in marble, and as a result, has a tendency to dissolve with the introduction of acidic materials. Over time, the acidic nature of rain has slowly dissolved the marble, and formed caves.
