GRAND TETON Creation of the Teton Landscape: The Geologic Story of Grand Teton National Park

Geology is the science of the Earth — the study of the forces, processes, and past life that not only shape our land but influence our daily lives and our Nation's welfare. This booklet, prepared by two members of the U.S. Geological Survey, discusses how geologic phenomena are responsible for the magnificent scenery of the Teton region.

Recognition of the complex geologic history of our Earth is vital to the enjoyment and appreciation of beautiful landscapes and other natural wonders, to the planning of our cities and highway systems, to the wise use of our water supplies, to the study of earthquake and landslide areas, to the never-ending search for new mineral deposits, and to the conservation and development of our known natural resources. Who can say, in the long run, which of the many uses of this knowledge is the most compelling reason to seek an understanding of the Earth?

This booklet is based on geologic investigations by the U. S. Geological Survey in cooperation with the Notional Park Service, U.S. Department of Interior.
