I’ve been looking at these scales, or chatter marks as they are called, near Dawes Glacier for years. I love showing them to our guests. They always feel impactful to me. Maybe it’s because they weren’t yet exposed when John Muir visited Dawes in 1880, or perhaps it’s just Mother Nature’s raw talent as an artist. Whatever it is, this part of Endicott Arm is one that I always enjoy gazing at.
