Geo 365: August 6, Day 218: Soft Sediment Deformation

Looking down-dip, some deformed sediments in the Coaledo Formation in the eroded terrace at Shore Acres State Park. There's a large ball-and-pillow structure below and around the lens cap, and a flame structure- albeit not very well developed- on the right side of  that feature. On the left, a thin dark bed has been broken and lifted up. And above, tilted strata have been eroded off then re-covered with new layers, and the whole package deformed into undulating waves. The lens cap is 52 mm in diameter.
