DescriptionMap of the state of Connecticut, bordered to the north by Massachusetts, the east by Rhode Island, the south by the Long Island Sound, and the west by New York. The different types of Triassic and pre-Triassic rocks in the state are marked on the map with lines and abbreviations of different kinds of rocks, the meanings of which are provided in the "Geological Explanation" below the map. To the left of the map is the legend, which contains explanations for the different lines that mark states, counties and towns; the symbols that denote cities of different sizes; the lines that correspond with different roads and trails; and the symbols that mark elements of infrastructure.
On the verso, there is a much longer explanation of the different types of rocks found in Connecticut than the short key on the recto. It is divided into three categories: pre-Triassic rocks found in Western Connecticut, pre-Triassic rocks found in Eastern Connecticut, and Triassic rocks. The rocks are listed in alphabetical order within categories, and each entry contains information about the physical properties of the rock. In the center of the sheet is a description of the list of sources used in creating the map, and below it is a small map of the state featuring the last names of the authors of those sources in the parts of the state from which the information on the geology came.
