At the risk of Spamming this group here are three posts that detail the Flower Walk we did this last Sat April 15th on my Ranch in Northern California.


We started up Red Barn Creek which was very full and a bit hard to cross.   As usual the pace was extremely slow at first as everyone stopped and talked about every single new plant (it seemed!)  Eventually we entered the big meadow across from Devil's Den.  One of the members, using her field glasses spotted "a yellow flower" so we all trooped back across the stream and up into Devil's Den.



Devil's Den is an ever changing and eroding mass of highly Serpentine laced soil.  Serpentine rock is part of the mantle rock, not the earth's crust.  It forms in sea bottoms, fractures easily and is thrust up in our countryside as the continental plates collide.  It is full of Magnesium and thus is very hard to grow anything in.  Here the serpentine rock has mixed into this gravelly amalgam.  It erodes really quickly and nothing grows on it.



Here are two pictures of our yellow Owls Clover all tangled up in purple vetch.  They were way more brilliant yellow than either picture shows.





Chuck and Olly brought up the rear of the group as we climbed up and out of the top of Devil's Den.  It looks so smooth and green but the cows make deep hoofprints into the soft grey clay making walking is really rather difficult.

Yeah, that's pretty barren rock.

such incredible diversity and beauty as you jump state to state ... I've only ever driven through Cali sadly , there are SO MANY natural wonders to see there.

Looks like a great place for an outing, very scenic.

What a fascinating look at the landscape, thank you! Do the meadows depend on cattle grazing/human activity?

Ah, interesting, thanks! (Also your comment below about the soil and geomorphology.) I'd momentarily forgotten about fire as a natural shaping factor; its complete suppression is a problem in many areas with mediterranean climate I think.

What a fascinating photo series. I've never seen anything like that landscape before, with the Serpentine in it. I especially like the contrast of the Owl's clover and purple vetch in front of it.

So you have grey clay there...we have lots of orange-brown clay here in SW PA.

My goodness, what a story that was! I'm glad you one poor cow out of there.
