While on a recent trip to the Canadian Rockies, we could not pass up a trip on the snowcoach, the bus that takes tourists out onto a safe bit of Athabasca Glacier, part of the larger Columbia Icefields. I was hugely impressed with the extent of the glacier’s retreat since my first visit in 1962. When we arrived at the safe spot (…) I found this lovely bit of otherwise undistinguished lateral moraine. The light couldn’t have been more dramatic as it highlighted the erosion on the loosely packed till. The surface of the glacier itself is seen at the bottom of the photo.
