Prelude
The combination of geologic information with topographic maps can be very powerful in the description and interpretation of the Earth's geology and geologic history. Topographic maps are used to represent the Earth's surface, and are an important part of many types of field studies. Geologic maps typically are drawn on a topographic map base and portray the location, distribution, and age of many kinds of natural features, like rock units, mountains, faults, folds, mineral deposits, etc. They may also include information about subsurface features. Students at all levels in geology can learn to read, interpret, and construct geologic maps to better describe and understand the geology and geologic history of the Earth.
