Several cross-sections through micrite mounds can be seen in this cliff section. The bedding is picked out by bands of flint (dark). Note the difference between the parallel-bedded units, and the mounds showing beds dipping off on both sides.

Roll the cursor over the image to see some of the inclined bedding defining the mounds.

Scale: the cliff is approximately 70 m high.
