Saundersfoot to Swallowtree Bay geological structures Just south of Saundersfoot Harbour is a small thrust with a footwall syncline in Lower Coal Measures rocks. The anticline component of the fold couplet has been sheared out by the thrust. The rocks are mainly grey mudstones with brown ironstone bands and nodules, with thin pale grey sandy lamine in the upper part and to the bottom right. The walking stick is 0.9 m long.

Broad Haven (south) to Stackpole Head Viewed from just north of Stackpole Head, the narrow sea arches of 'Lattice Windows' form the headland at the south side of Barafundle Bay. In contrast to the gentle southerly dip of the Carboniferous Limestone at Stackpole Head, fold structures have resulted in an increasingly steep northerly dip at Lattice Windows.

Broad Haven (south) to Stackpole Head Viewed from Stackpole Head, cloud-streets of cumulus set off the land and seascape looking towards Barafundle bay just left of centre. To the right, the light grey Carboniferous Limestone gives way to cliffs of 'Old Red Sandstone'.

Broad Haven (south) to Stackpole Head The cliffs of Stackpole Head consist of Carboniferous Limestone gently dipping south. There are sea caves and other solution features visible: the prominent bedding plane just below the cliff top displays palaeo-karst pot-hole-like features. Caldey Island is on the centre skyline; Llanmadoc Hill and Rhosili Down on the Gower Peninsula can be seen in the far distance just above the headland.

Broad Haven (south) to Stackpole Head Mowingword Point was very colourful on this beautiful summer's day, with the contrasting orange lichens and purple Viper's bugloss.

Broad Haven (south) to Stackpole Head Viewed from Mowingword Point, Mowingword Bay, backed by Gun Cliff, is inaccessible except by sea or climbing down the cliffs (climbing equipment and experience needed). The prominent Pinnacle Stack is in the middle of the bay. Church Rock just offshore from Broad Haven (S) is visible in the upper left. The flat, Tertiary age '200-foot erosion surface' is well seen in this photo.

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?) This panoramic view shows the large size of the doline and consists of three landscape photos stitched together with Photoshop software.

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

Broad Haven (south) to Stackpole Head Just east of Broad Haven and Saddle Point is Box Bay with well developed sea-caves at its eastern end. Can you see the climbers? The rocks are Carboniferous Limestone. Box Bay is sometimes known as Sandy Pit Bay (after the doline just inland of the bay). Neither names are used on the Ordnance Survey maps. The headlands of Mowingword and Stackpole Head are at the far right. This is a panoramic view consisting of two landscape photos sticthed together using Photshop software. Also taken using a polarising filter. I'm pleased with how the clouds have turned out.

Broad Haven (south) to Stackpole Head Church Rock sea stack, with its steeple-like point lies just off shore from Broad Haven. This is a view from Saddle Pooint at the eastern end of Broad Haven. The rocks here are Carboniferous Limestone. There are two Broad Havens in Pembrokeshire. This is the southern one (the other is in the west in St Brides Bay).

Broad Haven (south) to Stackpole Head This is a view from the coast path at the eastern end of Broad Haven, looking west over the glorious beach. I liked the patterns of the waves and swash lines on the sand as the tide receded. There are two Broad Havens in Pembrokeshire. This is the southern one (the other is in the west in St Brides Bay).

Broad Haven (south) to Stackpole Head This is a view from the western end of Broad Haven, looking east towards the Carboniferous Limestone cliffs of Stackpole Head. Caldey Island is on the distant skyline. There are two Broad Havens in Pembrokeshire. This is the southern one (the other is in the west in St Brides Bay).

A beautiful summer's day on the Pembrokeshire Coast Path above the western end of Marloes Sands, looking over to Gateholm Island and Gateholm Stack, with Skokholm Island on the skyline. The rocks here are Devonian age 'Old Red Sandstone'. Such a contrast in weather to when I was last here!

A view over the small inlet of Victoria Bay near Marloes in Pembrokeshire. Slabs of Silurian age sandstones dip at about 40° to the south.

St Brides Haven in Pembrokeshire shows off her colours! Red sandstones and mudstones of the Devonian age Old Red Sandstone contrast with the turquoise sea on this beautiful summer's day. The rocks are gently folded into a series of open anticlines and synclines, visible on the far side of the inlet. The white building is Cliff Cottage (available for holiday let).

The prominent building on the left skyline is St Brides Castle, a 19th-century baronial country mansion.
