Fox Hole Anticline - northern limb jointing with candle
Structural geology of Little Haven and The Settlands
The cliffs from Little Haven to Broad Haven (and northward) display a spectacular range of geological structures, folding, faulting and thrusting, mainly in the Lower Coal Measures. The relatively weak mudstone and shale-dominated sequences show much incompetent deformation: tight, thrusted and overturned folds, in contrast to the thicker, stronger, sandstones which have formed relatively open and concentric folds.
The northern limb of the Fox Hole anticline forms the southern headland of The Settlands bay. The style of folding is open and concentric, largely due to the thick (approx 70 m in total) and competent (strong) nature of the sandstone of which it is comprised. At the western end of the headland the bedding dips at about 30° to the north, but this steepens along its length to become near-vertical at the eastern end of the headland.
This is a view looking head-on at the steeply dipping bedding surfaces. The bedding is cut by nurmerous joints (fractures) which in this case has been enlarged by erosion to form a shallow sea cave at beach level. Someone has lit a candle on a rack inside the cave. Perhaps a memorial to a loved one?

Earthwatcher club has replied to Amelia clubI guess your walls and buildings will be made from the Devonian age Old Red Sandstone, which can be very good for building stone, depending where it is from. it's possible that the large buildings like your church was made with relatively unweathered stone from good quarries, whereas field boundary walling stones may have been sourced from relatively shallow (and hence partly weathered) local pits and scrapes.
