Geo 730: October 29, Day 667: Cross Bedded Astoria Formation

I'm told that the rock here, sediments under Columbia River Basalt of Elephant Rock at Seal Rock State Park, are also Astoria Formation. The tide was out far enough at this point that we could get down to beach level to get a good look at them. I was immediately struck by the terrific cross bedding visible below and to the right of the lens cap. In fact, I need to assemble a series of photos of these beds into a panorama for tomorrow.
