How nature sculpts a cliff

In case you haven't seen it, shown in the video below is a cliffside at Pictured Rocks National Lakeshore on Lake Superior changing the scenery while being filmed.

It's called erosion, but rarely is it this dramatic.  Landslides, rockfalls,volcanic eruptions, flash floods -- they have a big impact, and they happen fast (most of the time, at least).

As we tragically are aware, it's just not a good idea to be in front of or under these circumstances when they happen.  Fortunately, no one here was.
