The SF Chronicle reports that a deal is in the works to open roads and trails in the SF Water District’s vast watershed lands on the peninsula to everyday people like you and me. Long have we gazed at those hills, and wondered about the animals and plants that find shelter there – it’s like a Lost World, right in the middle of our information age hubbub. I wonder if it would truly be lost if we let more people in there. Frankly, the track record of letting people in to wild places is not so hot. And once inside, it’s really hard to get them out. Maybe they’ll reach an acceptable middle ground, where some trail routes exist, such as connections for the Bay Area Ridge Trail, but large areas can remain undisturbed. Probably the best way to do this is to make any entrance path from a trailhead steep and narrow, with limited parking availability. Here’s an old cell phone photo of Cahill Ridge from March 2006, in the early morning following a rare low-elevation snow event.
