South America, Chilean and Argentine Patagonia, Don Bosco, Southern Patagonian Icecap

Don Bosco, Southern Patagonian Icecap. Noel Cox, Steve McAndrews, Randy Udall and I spent six weeks from early March to mid-April in the Cordillera Darwin and along the Upsala Glacier. The usual murderous climate gave us only 2½ days of good weather and kept us from our objectives: Riso Patrón and unknown peaks on the Pacific side. We spent twelve days reading in a buried snow cave at our furthest point, on the flank of Cerro Don Bosco (8251 feet), which we climbed by its east ridge on a single day of good weather, April 15. This route has previously been climbed by the Argentines Peterek, Klenk and Pas tewski on February 3, 1957. Eric Shipton and Jack Ewer made the second ascent.
