Alger, WA - A 3-in-1 design

I'm can't recall three different designs connected to each other like this. A small circular pattern, and then following the path to a second one, and then a third one. And all tucked away behind a nondescript community center building. The labyrinth itself is on the bank of a small creek - Silver Creek - so it's fairly well camouflaged. This is in Alger, Washington, also about an hour north of Seattle, just off of I-5.
