The Tide Pool of Saint-Malo

(As a sort of marginalia to our counter Aquatics Complex is this tide pool in Saint-Malo, Brittany, France, between low and high tides. At the far end jutting out is a diving platform. During high tide, this Atlantic exclave rejoins the sea, as can be seen here, and the diving platform appears like a Gallic Loch Ness monster or an avian cryptid on a dawn flight, its Archaeopteryx wings skimming the surface.
