The part of the trail where this cache is located goes past a nice second growth redwood grove. It is one of my favorite sections of trail in this area.
When I first saw these trees I thought "that's a giant's teeter totter!"
The cache is an ammo box hidden in a common manner. For anyone who has found a cache in the woods it shouldn't be hard to find.
The trees wreak havoc with the satellite signals, so the hint is a spoiler.
Good starting points to get there are from the parking lot on Camp Pomponio Rd (a short drive from the Russian Ridge/Skyline Ridge parking area) or (the easier hike) via the Pomponia Trail from Portola Redwoods S.P.
Thanks to GoGoJo for providing the cache container!
Please do not log a find if you do not find the container!
