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.
