Lower Shoreface refers to the portion of the seafloor or sedimentary depositional environment that lies below everyday wave base (see also upper shoreface). In this portion of the coastal environment, only the larger waves produced during storms have the power to agitate the sea bottom. Between storms, finer grained sediments accumulate on the seafloor, but during storms those sediments get suspended and moved around, resulting in a sedimentary structure form described as hummocky cross-stratification.
