The Pine Tree State GeoArt series will take you on a short trip not far from Stratton. The road is passable by most cars, but bikes and e-bikes are fine too. There is also about a mile or so of walking. Each cache will highlight something interesting about Maine.
Maine Limestone Caves
There are a number of small bands of limestone found in the southern part of Maine and most of the northeastern part of Maine is limestone. While there are large deposits of limestone most of it does not favor the formation of caves. There are some small pockets of limestone that do have caves which include Indian Pond Cave, Marble Pond Cave and Enchanted Cave.
