This is an article discussing erosion along the Beaufort Sea. However, the really interesting part is the short video taken in July 2008. It uses time lapse photography and within the space of a month you can see the erosion. Normally, we think of erosion as process that takes decades or centuries not days. I would use this to have student think about how quickly “normal” (as opposed to catastrophic events which everyone knows happen quickly) can fashion the landscape. To do this I would probably ask how long they thought it would take typical processes to cause a noticeable change in landscape features. After a brief discussion I would show the video.
