Author Description

The National Parks of the United States preserve our nation's iconic landscapes and some of the finest examples of geologic heritage. From glaciers to caves, volcanoes to canyons, or mountains to coral reefs, the nation's geologic features and landforms have been an important part of the American experience throughout its history. The geologic features found in our national parks are a testimony to the Earth's complexity and dynamic nature; a planet that has been in a continuous state of change since its origin 4.6 billion years ago. The landscapes and awe inspiring geological features we observe in the national parks are merely snapshots in time as Earth continues its course of change as the result of interactions among the planet's many internal and external processes. The landforms and geologic structures within our national parks have a story to tell about an area's geologic history and tectonic setting. Geology of National Parks teaches how to recognize landforms and rock formations within a national park; thus, students will begin to read and interpret the geologic story behind the scenery which extends to scenery beyond the parks to their own backyard. Students will also recognize that the plant and animal communities in an area along with the human history are linked to the landforms through the habitat, resources and shelter they provide.
