Geologic interpretation of seismic data, relocation of Route 3: cut, stations 364-382 in Billerica, Mass.

Geologic and seismic studies were made of this site in October 1951, primarily for the purpose of obtaining data what would aid in establishing a grade for the proposed highway. A report on the geology of the site together with the interpretation of the seismic data that were obtained at this time was submitted by James E. Maynard and Robert M. Haslewood (file report of October 1952). Additional seismic work was performed at this site in Maroh 1953; Mr. M. E. Chandler, Engineer, Massachusetts Department of Public Works, operated seismic equipment at this time. This later work was done to obtain information that would augment the data of the preliminary survey sufficiently to permit estimates to be made of the quantities of materials to be excavated from the cut. This report contains the geologic interpretation of the supplementary seismic data that were obtained during the Maroh 1953 survey. The work was perfromed as a part of a cooperative project of the Massachusetts Department of Public Works and the United States Geological Survey.
