FLASHBACK PHOTO: WILLIAM HENRY JACKSON, NATIONAL GEOGRAPHIC STOCK Springs Eternal "Late that next afternoon we had our first close view of the enchanted land, when our party came upon the Mammoth Hot Springs," wrote photogra- pher William Henry Jackson, who accompanied explorer Ferdinand Hayden on his 1871 expedition to Yellowstone. Jackson packed, muleback, some 300 pounds of equipment on the journey, including hundreds of fragile glass plates upon which he developed images on-site. Yellowstone's thermal pools proved to be more than just photogenic, according to Jackson; they also helped speed the photographic process: "By washing the plates in water that issued from the springs at 160º Fahrenheit, we were able to cut the drying time more than half." His pictures were instrumental in persuading Congress to declare the area a U.S. national park---the country's first---the next year. ---Margaret G.
