A simple grab and go at the intro signs of the Thorton Creek Water Quality Channel.
From the sidewalk, read about the Thorton Creek Water Quality Channel and Seattle's 'Restore Our Waters' strategy before finding the catch that is within an arms reach. No need whatsoever to step in any of the shubbery, so please stay on the sidewalk.
You'll need a TooT to sign the log.
Then if you have the time, take a few minutes to explore the channel to experience this wonderful hidden green space located in the shadows of the buildings around it. If you have even more time, go visit the Watershed Pub located at the other end of the channel with its wonderfully long tap list.
That was fast - Congrats Bio-KK for the FTF.
3/26/22 Update - The prior style of the cache disappeared twice, so today I switched it up a bit. Hopefully a bit more stealthier to hide from the landscaping/gardening crew.
