Grassland covered in invasive European grasses suddenly gives way to serpentine grassland, with uncovered serpentine rocks. This will be covered in poppies and other native plants, come springtime. A bare Valley Oak spreads over a Coast Live Oak; a seripentine-loving Leather Oak also grows nearby. Beyond lies Stanford and Hoover Tower, SLAC steam, Palo Alto, SF Bay, and the East Bay Hills, dominated by Mt. Diablo. Grey skies blanket all. 8:05 am.
