As a service, we also host publications of the Vermont Geological Society and many USGS maps which were compiled for the 2011 Bedrock Geologic Map of Vermont.  The full list of publications is in the left navigation bar.
Reports are also listed  in the Town Index and in the Publications Catalog. The 2011 Bedrock Map was professionally printed; all other maps are plot on demand at $10.00 per map plate. Please be aware that these  do not use permanent ink or waterproof paper.
