Mud and Peat Deposits from Point Reyes Marsh

Photograph of cutbank outcrop at Home Bay marsh, showing the subsurface stratigraphy to 90-cm depth exposed during low tide. Holes about halfway down the exposure are from burrowing crabs populating a narrow zone at the transition from underlying inorganic mud deposits to overlying peaty mud to peat deposits.
