Duxbury Shale Reef @ Negative Tide
In February, a text message from my friend Erika reminds me to reserve tickets for a hike scheduled for the Birding Festival Weekend at Pt. Reyes National Seashore. We double down and get tickets for the Tide Walk on Saturday and the Secret Caves hike on Sunday. An easy morning drive to Bolinas takes us to Agate Beach to join the PRNSA (Point Reyes National Seashore Association) naturalists awaiting us with release forms and field guides for tidepools. We stop at the park information signs and learn that the Duxbury Reef is the largest shale reef on the planet. Impressed, we proceed down the sandy path to scamper along the textured brown rock in search of sea-life. The rugged shale expands as far as the eye can see north to south and the flat surface makes it easy work to dash from pool to pool pointing out green anemones both open and closed, various types of seaweed and grasses, and boring clams – named not from lack of interesting features but because they literally bore holes in roles for shelter. I am especially fascinated by the hole-strewn rocks left by boring clams as they outgrow their hole and move on to drill larger rocks. I am grateful to friends who find amazing things in my neighborhood that add to our growing collection of adventures on the Point Reyes National Seashore.
