This was kind of an interesting discovery at Bonny Doon. As I mentioned the hills are made of sandstone, and from my earlier photo, you can see that it is easy for people to carve graffitti into the rock. Another thing that has been done is carve these ridges into the rock to make it easier to get down off of the hills. The sandstone is very grippy, so one doesn’t slide down all that much, but on the steeper inclines these gooves have been carved so people can put their feet in them and, sort of, slide down.

Note from the future 10/19/2012: wow! Did I pull this explanation out of my ass, or what? Ha! It is kind of hilarious to read this many years later. A REAL geologist corrected me via the contact form and said this about the grooves:

I stumbled across your site looking for photos of where I live in Bonny Doon California. I saw the very nice pictures of the Moon Rocks you took.

Being a geologist, I could not resist pointing out that the grooves in the rock were(are) formed by water erosion not carved into by people for better footing.

Just though you would like to know.

Thank you for setting me straight! 🙂

Raf and I went on a little hike today at the Bonny Doon Ecological Preserve. I’ve blogged about that place before. This time we went to this area where there are some sandstone carvings. It was really hilly but fun to climb the sandstone hills. I took some pics that I will post this week.

Here you can see the view, but if you look closely you will see a peace sign carved into the sandstone. Only in Santa Cruz, eh?

Travel and Other Adventures

In keeping with our recent tradition, we tried out a new hiking spot over the weekend, the Bonny Doon Ecological Preserve. We didn’t have a map and I don’t like not knowing where I am going, but otherwise we had a good hike.

Bonny Doon Ecological Preserve is a special place. It is the home of a few endangered species such as the Santa Cruz Cypress (see picture), the Ben Lomond Wallflower, and the Silver Leaf Manzanita. I didn’t have my native california plant guide with me so I couldn’t really determine if I saw them or not. I’m pretty sure the picture that I have here is the Santa Cruz Cypress. There are only a little over 5,000 of these trees left, and most of them are here at this preserve! Interestingly, as a side note, I was browsing the current periodicals on friday and found a journal called “American Forests.” I grabbed the most current issue and opened the magazine to an article about the Santa Cruz Cypress. So of course I wanted to take the short drive up to Bonny Doon over the weekend to see if I could find this rare tree.

Sadly, a few months ago, the park’s neighboors ran a bulldozer through the park, destroying some precious plants. You can read about that here.
