Undammed Rivers Updates

Ian has an update on the Elwha and the most recent lowering of the Glines Canyon dam http://coastnerd.blogspot.com/2014/01/glines-canyon-dam-now-invisible.html.

Steve Stampfli has been documenting the post dam removal on the White Salmon and documents a recent cliff face collapse that was formerly submerged http://whitesalmontimelapse.wordpress.com/2014/01/29/landslide/#respond.

I suspect the cliff face may have pealed off due to freeze thaw action which would have been on pause when the cliff was submerged. Of course the driver is also slow undercutting by the river that formed the cliff in the first place.
