Myron Fuller's report on the The Geology of Long Island, published as Professional Paper 82, contains scores of line drawings, b&w photographs and small maps in addition to the following two impressive maps, each measuring approximately 62 x 25":

Topographic Map of Long Island, New York. This highly detailed map shows county divisions, roads, cities, towns and railroads. It presents the entire island extending to include New York City, Jersey City and most of Staten Island. There is also exceptional detail along the Connecticut shoreline to Bridgeport. The details are quite remarkable and include small villages, dirt roads or trails, railways, and much more of interest. Topography lines, at 20' intervals, are shown in brown, coastal wetlands in blue, and the Atlantic Ocean and Long Island Sound in green.
