Collection Overview: NCALM Project. PI: John Gartner, Dartmouth College. The survey area covers a 45 square kilometers along the Ashelot River, south of Keene and crossing West Swanzey, New Hampshire. Data were collected to quantify the geomorphic and sedimentological responses to dam removal. Repeat survey from 2011: West Swanzey, NH: Geomorphic Response to Dam Removal, Ashuelot River (2011)
