These photos show an area near Drew Point, along Alaska's northern coast. Taken on August 9, 2007, the photo on the left shows how ocean waves have undercut the land nearest the shore. Grassy turf extends out over a wave-cut notch. Taken on June 20, 2008, the photo on the right shows what often follows such undercutting: chunks of coastline tumbling into the sea.
