The seasonal spring "vernal pools" are the Santa Rosa Plateau's claim to fame. They bloom with all sorts of life during the few weeks after the rain each year. The blurry greenish thing on the left is, I believe, a fairy shrimp. It's less than an inch long. Note the well-developed collection of eggs in its egg sack, just about ready to weather a year (or more than one) of drought until the next rain. This shrimp is under several inches of water, near the bottom of a tiny vernal pool.
