| Description |
Sculpture on its grandest scale is seen in the face of the Earth where rivers work to carve the hills and valleys. Dr. Harbaugh’s guest is Dr. Arthur D. Howard, professor of geology at Stanford University, who served as geologist with the Fourth Byrd Expedition to Antarctica in 1946-47. With the aid of three dimensional models, they demonstrate the ways in which a narrow stream can shape a vast expanse of land which is dozens of times its width. They discuss the way in which an area of the Earth, just as a man, goes through the ages of “youth,” “maturity,” and “old age.”
