A. Monument near Brownville Maine made of slate from the Carrabassett Formation. After 160 years the lettering and guidelines are still sharp attesting to this rock�s resistance to chemical weathering.
B. Slate ledge (approximately 9 feet high) a mile south of Greenville, Maine. The slate breaks along cleavages where it is vulnerable to free-thaw processes. This is the same formation that has been contact metamorphosed by the Moxie Pluton further north and forms the mountains around Moosehead Lake.
