“…The most recent NEIGC trip was led by Eusden et al (2009) and covered aspects of the Ordovician to Carboniferous bedrock geology and apatite fission track cooling history of the West Branch of the Peabody River in Pinkham Notch and again the Randolph, NH valley. Added to this list are the four excellent NEIGC fieldtrips led by Tim Allen on the stratigraphy, structure, and migmatites of the Pinkham Notch and adjacent Carter-Moriah Range (Allen, 1996(Allen, , 1996b(Allen, , 2017(Allen, and 2017b) and a pioneering trip led by Hatch and Wall (1986) who first proposed the Silurian age assignment for much of the geology and made the initial correlation to the Rangeley stratigraphy in Maine.…”
