Coast of Puget Sound - Great Book about the Geology of Puget Sound

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.

Erratic Boulders of Puget Sound

"A glacial ‘erratic’  is a rock fragment carried by glacial ice and transported some distance from the outcrop from which it was derived, and generally resting on bedrock of a different type* [although glacial or alluvial sediment may directly underlie the erratic. " (source: NW Geology)

Many erratic boulders line the shores of Puget Sound. Some large erratics can be found in Seattle such as 4 Mile Rock off the south side of Magnolia and this one below off North Beach of Discovery Park.  Read more about erratic boulders  (source: NW Geology)

Possibly the most interesting erratic is Haleelts Rock on the north end of Bainbridge Island which has a petroglyph on it's north facing side. See pic below.
