THE NATIONAL GEOGRAPHIC MAGAZINE WHENCE MAN CAME TO DWELL UPON EARTH According to Hopi legend, the first human beings arrived from the Underworld by way of the Grand Canyon. © National Geographic Society Natural Color Photographs by Fred Payne Clatworthy A SUMMER DAY ON THE CONTINENTAL DIVIDE Although the picture was taken on June 23, there were still eighteen feet of snow along the sides of this road in Rocky Mountain National Park. Charges of T. N. T. are so placed in autumn that they may be exploded in the spring to loosen the packed snow. Without these explosives and a steam shovel to clear a way, some of the roads would be impassable until late summer.
