Geology Professor Léo Laporte gave a geology refresher class for Jasper Ridge docents. Here are photos. After a while, I became less focused on geology, and more on biology. See the nearby folder from the same day of the Vultures circling. And the images of a bee on a Fremont's Star Lily, & a butterfly on Yerba Santa, in "Adventures on a Smaller Scale".
