The brown 'flow' just left of center in this photo is a massive landslide that occurred high up in the Fairweather Mountain Range. Scientists from the US Geological Survey are calling this event one of the biggest landslides in the world in recent history, and perhaps the largest one ever recorded in Alaska. The slide was so large that it was detected by seismic monitoring equipment. I was able to fly over it several weeks later when the slide was still raw and exposed. This particular slide generated a signal equivalent to a 2.5 magnitude earthquake. Photographer: Sean Neilson
