The formation of Cusps on Chesil Beach, Isle of Portland. On the Jurassic Coast. Geomorphology

In certain sea conditions, the normally regular shoreline of the mighty Chesil Beach is transformed into miniature baylets called cusps. Waves gauge hollows in the shingle between protrusions called horns. Chesil is one of the most studied geological features on the planet, and is a gem on the Jurassic Coast on the UK's World Heritage site. Something for the geomorphologists.

Fabulous thanks Stuart, a mystery (to many of us) solved!
