Description
North Grand Canyon - Walhalla Overlook by Debra Martz There are two overlooks at this stop; one to view (with binoculars) the ruins of an ancestral Puebloan home and the other focusing on the geological puzzle of the Grand Canyon. Since I could not get a reasonably decent image using my 600mm zoom, I decided on a panorama of the canyon.
From the information sign: "Below you, the Colorado River curves in a broad arc as it turns west into the high Kaibab Plateau where you stand. In doing so, it has created both the Grand Canyon and an enduring geologic puzzle. The plateau rises thousands of feet above the lowlands to the east. Why didn't the Colorado simply avoid this plateau? Geologists have puzzled over this question for more than a century. The evidence shows the plateau rose millions of years before the canyon was cut. Although geologists are uncertain how, erosion had shaped the plateau's landscape so the Colorado River could make its grand entrance. Continued erosion, however, destroyed many decisive clues that would explain how the river did it. Geologists are still trying to fit the puzzle pieces together, but one thing is certain. Without the unexpected turn in the Colorado's course, there would be no Grand Canyon."
