Don’t know if the rock is serpentine in that location. The UC Botanical Garden (200 Centennial Drive, between the stadium and LHS) has a fun little serpentine section, though, with plants adapted to tolerate the heavy metals in serpentine soils. It’s in the California section of the garden. You can inspect the serpentine rocks closely without having freeway traffic whizzing by.

I used to pass by there early in the mornings on my way to work. I’d often see a small flock of white doves feeding on some mineral [i think that's what they were doing] in this cut. Have you ever seen that? or something similar? i wonder what kind of doves they were and what kind of mineral they were finding there…
