We have chosen a perfectly gorgeous day for a 13-mile walk, part of which is inside a protected area of the SF watershed. Our group today includes Beth, docent Bob, and Molly's son Alex. Bob is a volunteer who leads walks (and unlocks gates) on the Fifield-Cahill Ridge Trail, and he's a wonderful trail companion, as well. Thank you, Bob!
Here we are climbing up to Sweeney Ridge from the Sneath Lane gate. Behind us to the right is Crystal Springs Reservoir, which lies in the valley formed by the San Andreas Fault. We're on the Pacific Plate today.
Montara Mountain from the east. This 1,898-foot-tall granite peak has traveled northward a few hundred miles from the granitic formation that extends from Los Angeles to the Sierra Nevada. The base of the mountain has serpentine-rich soil derived from sea floor at the point where one plate moves under another.
This mile marker was used by a mountain lion as a scratching post.
Nine miles in; four to go! Thanks for joining us today, Beth, Bob, and Alex!
