Summary:

There's a tree stump that is gradually being progressively exposed (see photo).  I marked this with red paint.  This should be an excellent opportunity to measure the rate of dune retreat.  Wish I had thought about this a year or so ago when I first saw it.  I've been monitoring it for the last months and have taking photos.

Also, somthing else I will start doing and should've started years ago, that is, measuring dune profiles using an Abney level.  I'll begin this next month.  This is valuable data, easily acquired, and something we could ask CW'ers to do.

  • Looking north toward So. Columbia River Jetty - note summer dune profile.
