Exposed Serpentine

Exposed Serpentine
Since I've made so many references recently to serpentine rock and serpentine soils and the plants (like the one just posted) that grow in serpentine soils, I thought I post a picture of the rock itself taken in the Siskiyou Mountains of California. The rock is the greenish-black rock that is exposed in the picture at ground-level and running up into the rock face. It may contain toxic metals such as chromium, manganese, cobalt and nickel and also contains asbestos. Its greenish color has earned it the name "serpentine" and it is the state rock of California.

Super shot, Ron, and thank you for the info on it, as it was a good refresher for me from my college days. I'm an example of the old addage "A Bachelor's in Geology is only as good as the memory of the person receiving it." And I've forgotten 99% at this point! But I was always more of a "fossil guy."
