A couple of weeks ago D. and I went up the coast to Bolinas to see the tidepools at the Duxbury Reef State Marine Conservation Area at Agate Beach. And we took some pics (all by D. unless starred*).
Here is the path down to Agate Beach.
Duxbury Reef at low tide, full of nooks and crannies teeming with invertebrate life.
Anemones and turban snails in a pool.
A little crab gives us the skunk eye.
A big red crab (Cancer productus) gives no one the eye because it's dead.
Turban snails in various different pools.
Here's kind of a strange one, peeking out of its shell:
A tiny anemone covered with pebbles almost bigger than it is, and a snail called the Angled Unicorn (Acanthina spirata) peeks out of its shell as it feeds on algae on the bottom of the pool.
A holey rock caused by limpets scraping away with their raspy tongue-like radulae.
Limpet in its hole.
Baby barnacles await the return of high tide.
Then we drove up the side of Mt Tamalpais to find a semi-secret stone circle.
View from the flanks of Mt Tamalpais, looking south to the hazy blue hills (San Francisco) on the horizon to the left. Bolinas Lagoon is in the foreground.
Another view, looking southwest.
A bird's eye view of Bolinas Bay, with Bolinas Lagoon in the foreground, looking down from Mt Tam.
Late afternoon sun glints on Bolinas Bay. The Farallon Islands are near the horizon on the left.
Looking over the Pacific toward Pt. Reyes.
The northern flanks of Mt Tam.
Looking south toward San Francisco.
A raven flies over the mountain with a snake in its beak.
A grouping of boulders on Mt Tam's west side; not quite a true circle. Even so, some people go there to meditate among the stones.
Mt Tam's dry hills, not yet greened by winter rains.
Looking south across the hazy blue Pacific.
