Figure 2. Beautiful outcrop of the Kittery Formation. This wave-washed surface displays the greenish-gray and lavender-gray layers that make up the formation. Although they are metamorphic rocks, the original sedimentary character is well preserved. Beds of sandstone and siltstone from 20 centimeters to over a meter in thickness are characteristic of the formation. Originally horizontal, the layers are now tilted steeply to nearly vertical. White, weathered pods are calc-silicate rock, which represents an impure limy sediment.
