WONDER TRAIL

An Educational films corporation of America production available only to schools. "Scenic marvels in Sequoia and Yellowstone National Parks, although not identified. The commentary is quite limited and there is an orchestral accompaniment. 'Highly recommended for the grades from 4 through senior high school in the study of geology and geography. Specifically suggested for physical geography to stimulate interest in erosion, the formation of the contour of the earth and the tidal display elements. The superb photography will be of interest to classes in art.' Advisory committee"
