These Crozier cliffs are remarkably interesting.

The rock, mainly volcanic tuff, includes thick strata of columnar basalt, and one could see beautiful designs of jammed and twisted columns as well as caves with whole and half pillars very much like a miniature Giant's Causeway.

Bands of bright yellow occurred in the rich brown of the cliffs, caused, the geologists think, by the action of salts on the brown rock.

In places the cliffs overhung.

In places, the sea had eaten long low caves deep under them, and continued to break into them over a shelving beach.
