Yay for Sugarloaf! Hope you enjoyed the Adventure Lab. This should be an easy find. Have fun on your hike.
Please note you may "check out" a State Parks pass from your local Sonoma County Library.
For those of you that do not enjoy Adventure Labs, The Coordinates can be found by solving this puzzle. Hint: the puzzle is a puzzle. https://www.jigidi.com/created.php?id=bsvby9s3
