Geology For Those Interested:
Like BART hike 009 and 011, on this hike we'll mostly see rocks of the Franciscan Complex Melange Terrane but we will also enter, near the peaks of Mt Tamalpais, the Nicasio Reservoir Terrane and the Coast Range Ophiolite Terrane. Again, the same article linked in the past hike has a useful summary of the rocks and geology we may see:
And additionally, if you are interested in what an ophiolite is check this site for a good summary:
For some of my rock formation notes and geologic maps I found in the internet for this area and cut out for our amateurish use see:
