Soft-sediment folding - Alaska

These are some relatively young and unlithified sediments from the south shore of Cook Inlet, just off of Highway 1 in Alaska. You should note and trace: 1) some of the folded layers, 2) any place the original sedimentary lamination appears to have been obliterated, and 3) an upper truncation surface.

Questions that may arise include the following. What is the geometric character of the folding? What caused this deformation? Why is the lowest layer relativey unaffected?
