- Tour of Park Geology: Mountain Building. This site provides links to geologic 'tours' of national parks, monuments, and recreation areas of the United States National Park Service that are associated with major mountain building periods. The parks are divided into groups by mountain building events: Appalachian, Laramide, and others. Individual park websites feature general geologic information, maps, and visitor information. Where available, there are also image galleries, links to multimedia resources (books, videos, CDs), links to related websites, park-specific curriculum materials, and general information about the parks' education and intrepretive programs.
