Large cavities in triassic basalt sea cliffs. Known for having a large rock slide in the early 19th century.

This section of shore is not heavy mineralized, but small localized zones are productive. In the 1990s, a large fissure produced hundreds of fine specimens of analcime. Good heulandite, gmelinite, and natrolite specimens have also been found in recent decades.
