Maine is a small state in the far northeast of the United States, one of the New England States. It is part of the eastern mountain range, the Appalachias, and consists of various intenslive folded rocks. Unfortunately, for the existance of caves, they are almost completely crystalline rocks. Todays irregular coastline is a result of the last ice age, as the coastal area with its valleys was flooded by the rising sea. The typical caves are small but interesing, talus caves and fissure caves formed by tectonic movements, and all forms of erosional caves, especially sea caves along the 6,000 kilometers of coastline.
