Bedding surface showing large ripples in coarse sandstones. The ripples are symmetrical, and have bifurcating (branching) crests.
- Were these ripples formed by waves or currents?
- What is the approximate wavelength of the ripples, measured crest-to-crest? (Assume the geologist at front right is 1.8 metres tall)
- Under what conditions could such large wave ripples form in coarse sediment?
