Due to the many posts I've added about the geology and development of Puget Sound, fellow paddler Granville Paules sent me an out of print book that puts all the Puget Sound and Salish Sea geology into context.
If you want to learn how Dungeness or Ediz hook were made, how beach erosion affects your beach place bulkhead and many other things, check out this book, if you can find it.
