There's one part of town here that is basically a giant sand dune. Sits all by it self, no way it was deposited by the river on the other side of the valley. When I sent redi-mix trucks in there, they had to be all wheel drive to get around :lol:. The footings under the houses are like 8' deep :eek:. US 101 is on that same dune. I'd love to see the engineering involved in the 60s to do that. They built a new overpass in that neighborhood recently, all the foundations are twice the size of any bridge I've poured concrete for in the past.
