Climbing ripples

Climbing ripples form under specific hydraulic conditions, and tend to be canceled or eroded by the next flow. Sometimes they do get preserved though, such as in this example. This set is part of a turbidite, a sedimentary layer that forms at the foot of relatively steep submarine slopes. I can count at least seven different flows in this small interval (see coin for scale).
