Only by flying into its belly do you feel its awesome power. Sheer-walled canyons, thousands of feet deep, seem to swallow you alive. Climbers inching along its buttresses look like ants in a vat of sugar. Glaciers more than 25 miles long creep imperceptibly down its flanks.
Jagged icefalls create a frozen impression of inferno.
Airplanes circling its great amphitheaters look like flies in the Coliseum of Rome.
