Bedrock: Washington Park, Anacortes

Not long before I moved to Anacortes I joined a geology field trip that took us along the dramatic, rocky shore of Washington Park. From the loop road we came to a short stairway that led us down to a wave-worn bench of reddish-brown rock that looked like snake skin. Aptly named, the rock, I learned, was the metamorphic rock serpentinite, a bit of the earth’s mantle exposed and planed level by Pleistocene ice.

Overcome by the thought of all that time, I was in no hurry to move on.
