The 3D images are anaglyphs and require red and cyan 3D viewing glasses. These full-size images average 500 KB each and may be slow to download.

3D glasses

A search on the World Wide Web will yield many sites about anaglyphs and where to get 3D glasses. To learn more about how anaglyphs (3D images) are made, click here.

National Parks and Physiographic Provinces

Learn about physiographic provinces and the regional geology of the United States. Most national parks and monuments preserve geologic features and landscapes that are representative of the larger physiographic regions where they occur.

Click here to download a larger version of the map (or click on the map).

physiographic province is a geographic region with a characteristic geomorphology in which climate and geologic factors—over time—have given rise to a variety of landforms different from those of surrounding regions.
