This creates a cove, a circular area of water with a relatively narrow entrance from the sea.
Erosion is just starting to the west, where the sea has again broken through the Portland limestone barrier at Stair Hole.
The Dalmatian type, named from Dalmatia on the Adriatic Sea, features long offshore islands and coastal inlets that are parallel to the coastline.
The Adriatic Sea itself is a concordant landform, consisting of a body of water between parallel ranges.
These Dalmatian types normally occur in high energy environments from where there is eustatic or isostatic change creating a submerging coastline.
