The American West presented early photographers with challenges equal only, perhaps, to the technical challenge of early photography itself. Here is a sample of what the photographing pioneers captured and what they overcame to do it. CAPTION: Picture 1, "Photographing in High Places," ca. 1870 (above) William H. Jackson, pictured here with an assistant, photographed Yellowstone, the Grant Tetons, and other areas for the U.S.** GEOLOGICAL SURVEY. AN IMPRESSED CONGRESS SET THESE LANDS ASIDE AS NATIONAL PARKS. JACKSON MADE MANY OF HIS IMAGES ON 16" X 20" GLASS PLATE NEGATIVES WHICH WERE CARRIED OVER MOUNTAINS AND DESERTS ON THE BACKS OF MULES. BY THE TIME JACKSON DIED IN 1942 AT THE AGE OF 99 HE HAD TRAVELED THE WORLD AS A PHOTOGRAPHER, CROSSING INDIA BY ELEPHANT AND SIBERIA BY DOGSLED.
