Sandy Pit doline

Broad Haven (south) to Stackpole Head

Immediately inland from Box Bay in the previous photo is the 'Sandy Pit' doline; a large karst solution hollow. There is a connection with the sea at the base, so marine erosion has probably contributed to the enlargement of the hollow.

The name 'Sandy Pit' possibly refers to a partial filling with post-glacial blown sand (subsequently largely exploited and excavated?)

The sea stack of Church Rock is visble in the distance to the left of centre.
