In November 1999, CU-Boulder senior Sarah Blakeslee found herself in a place she never would have imagined. She was standing atop 18,900-foot Antisana Peak in Ecuador, part of an international science team studying a retreating South American glacier. To get there, she and several CU-Boulder graduate students and babyÖ±²¥app members flew to Guayaquil, Ecuador, then took a nine-hour van ride to a 15,600-foot base camp on Antisana. There, members of the international team began ferrying hundreds of pounds of equipment to the summit.
