STORMS AT SUBZERO TEMPERATURES SWEEP ACROSS THE HIGH ESCARPMENTS AND THE DEEP GORGES OE THE ANDES The valleys are filled from the deep snowfalls of winter, and the winds cause drifts of great depth. Over the rugged, sawtoothed ridges aprevail ing west wind drives fine, powdered snow high into the air and sweeps down again in tremendous gusts into the valleys on the east. The weather in high mountains is always terribly uncertain, not only to climbers and explorers, but to the travelers whoseek the lower passes. Many parties have been overwhelmed by sudden blizzards in crossing from Argentina to Chile.
