Oakland began with a marshy waterfront; sure it was full of fish and oysters, but you couldn’t do big-time commerce there to match the transcontinental railroad depot. So the marshes were filled and the shore extended into deeper water and passages dredged until Oakland had a splendid harbor, and it still does today. Thankfully, we’ve even had the drive and funding to recreate a small example of a working shoreline here at the new Middle Harbor Shoreline Park . . . we hope. If this kind of work is done with a geomorphologist’s guidance, there’s a chance that it could age gracefully instead of sinking or slumping or washing away. With that hope, I dub this piece of land Middle Harbor Point.

Don’t know how long this URL will last, but ANG newspapers covered that subject just the other day: http://www.mercurynews.com/breaking-news/ci_15548021
They have paleontologists contracted to examine the excavation for as long as the fossils last, probably until the bore hits basalt.

I just drove through the Caldecott tunnel 4 times the weekend before last and I thought about this. I wondered if anyone was looking at the dirt that was being taken out. Has anyone found anything interesting?
I was just visiting the Bay Area but I live in the foothills of the Sierras and if I had a bore dug on my property I would probably hit the Mother Lode.
Also, how safe is the old tunnel, geographically. I would hate to be in it during a major earthquake.

Levi, the local geological society would love to have a chance to visit the work site. Write to me at geology at about dot com if this looks like a possibility.

Hey all.I just wanted to say that I have been seeing some fresh geology at both the eastern and western portals of the Caldecott Tunnel. I am working as a filed paleontologist/geologist for the 4th bore for a month now and have been privileged enough to see first hand rocks from auger spoils 0-95 feet below ground surface! Interesting stuff!
