DYK? The Puget Sound watershed includes three active volcanoes, which is awesome.

Is it found in Puget Sound?

The Puget Sound and Salish Sea watersheds contain many incredible geographic features, but it’s not always easy to tell which ones are truly part of the region. Does Puget Sound really include three active volcanoes? (Yes! See above.) How far north does the Salish Sea extend? And does that reach as far as Canada’s wonderfully named Octopus Islands? (We would hope so.) To help answer questions like these, we have created a simple overlay in Google Maps that includes the geo-referenced boundaries of our ecosystem. We hope you will bookmark it and start exploring right away.
