As she carefully packed the last of her leather-bound journals into the archival boxes destined for the university museum, Dr. Helena Vance paused over a faded photograph from 1968. It captured a young girl standing at the foot of the Athabasca Glacier beside her father—a moment that had set her entire career in motion. Decades later, that childhood fascination culminated in her groundbreaking 1989 expedition to Greenland, where her team extracted ice cores containing ancient atmospheric data. The publication of her paper on abrupt Holocene cooling shifts in 1993 cemented her reputation, but it was during a subsequent trip to the Canadian Rockies in 1997 that she first observed the rapid retreat of the ice she had studied for so long.
