[Gutenberg 51048] • The Geologic Story of Canyonlands National Park

Excerpt from The Geologic Story of Canyonlands National Park

Unless credited to others, for which grateful acknowledgment is made, the color photographs were taken by me. Most of these were taken on 4 by 5 - inch film in a tripod-mounted press camera using lenses of several focal lengths, but a few were taken on 35-millimeter film. Unless credited to others, the black and white photographs were kindly loaned from the Moab and Arches files of the National Park Service. The points from which most of the photographs were taken are shown in figure 19.

Although Major John Wesley Powell was not the first geologist to view the canyon lands, his two daring boat trips down the Green and Colorado Rivers in 1869 and 1871 made history by bringing to light the first descriptions of the geography and geology of what was then the largest remaining uncharted wilderness in the United States. Many landmarks along the canyons in the park were named by Powell and his men during those explorations. J. S. Newberry is thought to have been the first geologist to view the canyon lands - at least he seems to have been the first one whose observations were recorded but the more comprehensive findings of Powell (1875) were the ones that made history.
