Geology (Unit 2) - Geologic Maps

Geologic Maps

Geologic maps are important tools for understanding the distribution of rocks along the Earth's surface and for identifying particular rock units or formations in the field. Subsurface geology controls availability of water, influences vegetation, and plays a large role in where we can build our homes and businesses. Not only are geologic maps economically important, they also help us determine the geologic processes that shaped the landscape.

Geologists throughout history have used many different methods to create geologic maps, from satellite analysis to careful field investigation. In this unit, you will make a map using data comparable to those collected by a field geologist. Map locations and "rock samples" will enable you to make your own geologic map of the Florissant area.
