Learn how to read a geologic map. Some of the maps in this chapter can be printed on poster paper from large PDF files found here (opens in a new tab).These maps provide a good overview of the geology of a region, but necessarily simplify or omit many fine details. Geologic maps use a combination of colors, lines, and symbols to depict the relative age, composition, and relationships among rocks and sediments at and near the earth’s surface. Includes 7.5', 30x60', and 1x2-degree quadrangle ...
