Thank you @snook!

As you can probably tell, rocks are near and dear to my heart... we have a house full of them.

Where we live now — in western Washington — it was close to the edge of the Cordilleran Ice Sheet, which pushed down from both Alaska and Canada, as well as from the east when the ice started melting. The most notable glacial remnant we have is the Hood Canal, which is the longest and deepest fjord in the lower 48... and it is right around the corner from us, making for some great beach combing.
