Official Photograph, U.S.Army Air Service THE AVIATOR'S SIDELONG GLANCE AT MOUNT WHITNEY, 14,501 FEET, LOFTIEST SUMMIT OFTHE UNITED STATES OUTSIDE OFALASKA "Mount Whitney differs from all other mountains that we have seen, in that it is one of a seriesofprominences located on abroad, extremely high base. This base is a part of the main body of the Sierra Nevada Range, extending far to the north and south; itcomes up rather gradually from the west and is several miles wide on top, dropping off quite sharply to the east. A tail wind wascarrying us along at 14,000 feet and the ground was passing uncomfortably close underneath at the rate of 140 miles an hour, or better than two miles aminute. Owing tosome peculiar down currents, the plane was unable to rise above the top and it was necessary to skim very close to the surface ofthe mountain adjacent tothe highest peak." -Stevcns and Macready.
