The southern shore line of the Rubuds has a deceiving appearance, the dense lush coastal vegetation appears to spread out on to the beach, however what appears to be sand is in fact an algol matt covering what can be very deep algol peat - thick gooey smelly mud. The strength of the crust can be deceptive as is often covered further, by deposits of seagrass detritus that constantly washes ashore and forms the mass of the decaying vegetation, it does not support a persons weight.
