We are pleased to make Dr. Margaret D. Thompson's bedrock geologic map of the Newton 7.5' quadrangle available. This map has been peer reviewed, and represents decades of field mapping and careful geochronology to delineate the stratigraphic distribution of units within the Boston Basin.
We've upgraded to a new platform to better serve your needs- we're now more able to keep the website updated and working correctly. Features of our new website:
We are very pleased to announce the formation of the Massachusetts Geological Society: a grassroots effort by multiple geologists in the Commonwealth to create a place where folks can come together and talk about, and see, all of the great geology Massachusetts has to offer.
In 2014 the MGS returned to the Hudson 7.5' quadrangle to complete bedrock geologic mapping there started in 2004.
The MGS has published a new onshore-offshore surficial geologic map of the Newburyport East and Ipswich quadrangles. It is available at:
The MA state bedrock geologic map in addition to other natural resource and political data is now available right on your iPhone.
