We had risen early to arrive at Margerie Glacier as the sun was coming up, lighting the face from the side. Then we waited. Which is what just about everyone does. It is a Glacier Bay tradition, to sit on a boat in front of a tidewater glacier and wait for it to calve. Not all waits pay off with 'the big one', but many do and regardless it is always time well spent, waiting with the mountains, the sea, the glacier. We got lucky and had just enough warning of small ice bits starting to fall that I was able to catch the moment in motion. The next photo shows the spectacular splash. Photographer: Bill Eichenlaub
