A 1:24,000-scale geologic map Database of surficial materials has been released by the USGS for Massachusetts. This has been a major effort by the Massachusetts Geological Survey, in collaboration with the USGS, since 2002. The database and map represents the culmination of nearly 80 years of state-federal cooperation and research. The companion statewide Quaternary map of Massachusetts is underway and should be published in the next few years!
