I found one of these in Briones in Martinez. If you follow Reliez Valley Rd, you will eventually pass a farm and see a sign for Briones, head up in and its not far from the entrance.

Heres a link to my pics of it:

If anyone can give me an idea of where the other 2 are I’d love it thanks!

Thanks for replying to my post on 10/21. I've checked Google Maps and maybe I'm missing something, yet the directions I need aren't there. I'm looking for the exact trail to follow and the distance from the visitors center to get there. Without this information, it's like a needle in a haystack for me. [Just google "sibley labyrinth"]

I've been told there are 4 labyrinths here at the park. I've only found one with luck. I haven't found the one pictured above. Does anyone have explicit directions of how to get to this one? Or, do you know of any guided tours to get there? I'm a true labyrinth lover, but not at all fond of hiking in circles. I really like to know where it is I'm going. I've noticed that none of the Park's literature even mentions or directs you to the labyrinths, why I don't know. Yet, it would seem reasonable that they would and could. Any help/guidance is really appreciated? Thanks! [Look for the huge pit. Also, it's easily visible in Google Maps. The park's literature doesn't mention the labyrinths, and rightly so, because they're not one of the natural or cultural features the preserve was created to protect.]

I used to go up to that quarry in the winter to see if the pond had frozen over; it was fun to slide rocks across and break the ice. I was irritated when someone built the labyrinth, but what the heck.
There’s a lot of interesting stuff to see as you go down that canyon, and if you skirt south into Huckleberry reserve there’s even more intersting remnants of human occupation. There’s some truly ancient old cars in a remarkable state of preservation on the backside of the ridge.

Hey Andrew! This is a very cool site, and I also checked out your About.com page too. I’m going to be exploring that quite a bit in the coming days. I wanted to say thank you for linking my page on your blog. Apparently I’ve been getting a few visitors from you, and it’s always great to have the company! Keep up the good work, and I’ll link to your page after work tomorrow.

Best,
Jess

Debby, I’m not yet familiar with the Wildcat Canyon trail, but the stream runs through nonmarine sedimentary rocks of the Orinda Formation on both sides. The openings are probably related to weathering, like you see on Mount Diablo where an outer shell of the rock is hard but underneath it’s less well cemented, so it weathers out in pits. The official geologic name for this kind of formation is tafoni. But as I said, I haven’t walked that trail yet.

Hi Andrew,

I walked in Tilden a few times, on the Wildcat Gorge trail running below Lake Anza. On the left side, you see some major rocks that look very volcanic with large openings. I’m curious if this is possible?

Thanks,
Debby

that labyrinth has been there at least 20 years, if not longer.

I just went on that hike last week and was wondering about that labryinth … now I know it’s aliens ;)

Now that I live in the East Bay, I’ve been using this blog for planning my future East Bay hikes … thanks!
