This DEM is of bare-earth returns from a LiDAR survey of the Nashua River watershed. The area shown is of Shirley, MA, and beautifully depicts the juxtaposition of drumlins, an esker network, and other glacial deposits overlying areas of shallow bedrock (NE part of photograph). The floodplain of the Nashua River can be seen in the SE corner. Route 2 is just south of the image.
