You are here You are here

You are standing about 3/4 of the way up the cliff (blue arrow), looking in the direction of the green arrow.

The sediments exposed here are poorly consolidated interbedded sands, silts, and mudrocks. You dig a trench to expose a fresh face. In this trench can be seen a sequence from an erosional contact, up through mudrocks with fossil molluscs, to sands with trace fossils. The angular unconformity with the underlying folded sediments is visible in the lower left corner of the picture.
