Land use planning, resource evaluation, groundwater issues, and geologic hazards all require comprehensive understanding of geology. Mapping of earth materials, features, and structures is not done in Vermont by remote sensing. Mapping is done on foot and we seek to collect as much data as possible in our limited field season. We are very grateful to the many Vermont landowners who annually allow us on their land to investigate Vermont geology.

The New Bedrock Geologic Map of Vermont (released April 2012)

The bedrock map, the first complete map since 1961, makes available to the public a geological map based on work which incorporates the understanding of plate tectonic theory. Authors of the map are Nicholas Ratcliffe (USGS), Rolfe Stanley (UVM, posthumous), Marjorie H. Gale (VGS), Peter Thompson (UNH) and Gregory Walsh (USGS) with contributions by Norman Hatch (USGS), Douglas Rankin (USGS), Barry Doolan (UVM), Jonathan Kim (VGS), Charlotte Mehrtens (UVM), John Aleinikoff (USGS) and J. Gregory McHone. The map incorporates detailed field studies conducted over 30 years by more than 60 geologists, including many who were students of Doolan, Stanley and Mehrtens at UVM. The map was released on April 11, 2012 with a 2011 publication date.To see the evolution of the map, please click here. Click the main link above to see the map, press releases and links.
