Geologic interpretation of seismic data, relocation Route 1 cut, Stations 25-36 Ballard Estate in Topsfield, Mass.
Abstract
This investigation was undertaken to determine the surface and subsurface conditions between stations 25 and 36 of the proposed relocation of the Newburyport Turnpike, Route 1, Topsfield, Mass. Reconnaissance seismic work was performed at the site in September 1949. Because that work showed bedrock near the surface over an extensive area where a deep cut was to be made, a more detailed program of seismic work was performed in September, October, and November 1949. This report comprises all of the seismic work performed at the site. It was done as part of a cooperative project of the Massachusetts Department of Public Works and the United States Geological Survey.
