摘要：Charlie Roots is a 56 year old field geologist with the Geological Survey of Canada (GSC) who lives in Whitehorse and is based at the Yukon Geological Survey, a territorial government organi- zation. This is the story of my three brief encounters with Charlie, each separated by an hiatus of more than 15 years. Our most important and recent encounter was wordless—no meeting, no phone call, no email—the perfect crime. Now, I must admit at the outset that when I learned in school that much of the Yukon had ‘escaped’ Pleistocene glaciation, I wrote it off for my purposes as an area of good soil and bad outcrop. I was mistaken.
