Ringstead Beach is protected by a reef, which dries out at low tide, and this makes it ideal a fair weather anchorage for small boats.
Further West along the Jurassic Coastline near Osmington Mills, is the intricately weathered Bran Ledge, part of the Corallian group of rocks which were laid down around 155 million years ago.
The cliff section here has fossil oil deposits seeping from within, the remains of what was once a large oilfield.
The wreck of the steam powered coal barge, The Minx, lies on Frenchman's Ledge after drifting across the bay from Portland Harbour one night in 1927.
The landscape of Osmington Mills is continually on the move, mud slides and cliff falls are common, particularly during the winter when rainfall adds to the weight of the overburden.
Like Bran Ledge, the Osmington Oolite is also a Corallian rock, and these stretch across the bay in amazingly straight lines.
Also at Osmington are the Trigonia Clavellata beds. These hold perfectly preserved shells of molluscs and bivalves.
As always, the video ends with a spectacular sunset sequence, a fitting finish to this beautiful coastline of the Jurassic Coast.
