Rickets Head end-on view

Rickets Head end-on view
Nolton Haven to Newgale
The small Nolton-Newgale coalfield is separated by faulting from the main Pembrokeshire coalfield. It lies mostly within Pennant Sandstone Formation of the Upper Coal Measures rocks.

An end-on, westerly view of Rickets Head with St Brides Bay in the background. The present-day profile of the headland is a result of former coal mining activity and the removal of overburden to access the Rickets Head Vein coal which cropped out at the base of the sandstone which comprises the up-standing pillar of rock.

Stratigraphically, the rocks of Rickets Head are the highest (youngest) in the Carboniferous sequence of the Pembrokeshire coalfields.

The coast path climbs up over the disturbed ground and spoil heaps visible in the foreground.
