Label TextThe Connecticut Geological and Natural History Survey was established in 1903 to study the geology, botany, and zoology of the state. One of the earliest publications of the survey was this Preliminary Geological Map of Connecticut, which uses different colors to illustrate the different types of rocks that make up the state. This important map was first attempt to address the geological makeup of the entire state since James Gates Percival's pioneering 1841 report. Subsequent investigations of the state's geology invariably refer back to these two ground-breaking studies.
