A walk on Houndkirk Moor 24

A cool morning with frequent showers, clearing to sunshine by the afternoon.

Looking northwards to Houndkirk Hill from the Houndkirk Road. In the distance are the green-clad tower blocks in the Gleadless Valley on the south-east side of Sheffield, and the wind turbines of the Penny Hill windfarm south of Rotherham.

The clear afternoon light brings out the shadow detail of the scarp edge of Houndkirk Hill, composed of Namurian age ('Millstone Grit Series') Chatsworth Grit.

The southern portion of the Houndkirk Road offers fine views to the south and west into the heart of the Peak District. In the middle distance is the flat top of Higger Tor with its fringing crags of Namurian age ('Millstone Grit Series') Chatsworth Grit.

On the distant skyline is the high plateau of Kinder Scout, 12 miles distant.

A cool morning with frequent showers, clearing to sunshine by the afternoon.

The southern portion of the Houndkirk Road offers fine views to the south and west into the heart of the Peak District. In the middle distance are the gritstone tors of Mother Cap Stone, just left of centre, and Over Owler Tor, to the right. Like Houndkirk Hill and Houndkirk Edge, these are composed of Namurian age ('Millstone Grit Series') Chatsworth Grit.

On the distant skyline are the high moorlands of the Derbyshire-Staffordshire border, beyond Buxton.

A view north-east from the stone shelter in the previous photo, over the wide expanse of Houndkirk Moor. To the left of centre in the middle distance is Houndkirk Hill. The rocks to the right of centre form Houndkirk Edge. The straight scarp edge marks the line of a fault which runs along the foot of the scarp in a NE-SW direction.

Both scarps are composed of Namurian age ('Millstone Grit Series') Chatsworth Grit

Houndkirk Hill (elevation 389 m) is a compact feature with a prominent scarp edge facing north west. The scarp edge is an outcrop of Namurian age ('Millstone Grit Series') Chatsworth Grit.

The distant scarp edge on the right skyline is informally known as Houndkirk Edge, although not named on the Ordnance Survey maps. It is composed of a lower stratigraphic bed of Chatsworth Grit.

River Porter waterfall in spate: video clip

A short video of the River Porter waterfall in spate on 8th November 2019, following a few days of continuous rain.

Sorry about the slight tilt - the tripod shifted and I wasn't able to correct it during processing.

One of the secret places of Sheffield's countryside, this waterfall is in the upper reaches of the River Porter between Ringinglow and Fulwood Mills. Here the Porter flows over a 4 metre-high bench of Redmires Flags, part of the 'Millstone Grit' series in the Upper Carboniferous.

There was perhaps even more water coming over the falls shortly after the notorious Sheffield floods in June 2007:

But normally it is quite a docile river, looking like this in low-flow times:

Swallowtree Bay anticline-syncline couplet: detail 9

Saundersfoot to Swallowtree Bay geological structures

Detail view no.9 of the asymmetric anticline-syncline couplet in Lower Coal Measures sandstones and siltstones, just south of Swallowtree Bay.

This photo shows the asymmetric syncline of the fold couplet pair. On the left, the fold limb is vertical, becoming overturned towards the top of the photo. The opposite limb dips gently to the south (right). The sandstone beds show channelling and thickness variations, especially just above the top of the walking stick. The sandstones also dispaly a strong fracture fan cleavage perpendicular to the bedding, in contrast to the darker, weaker, darker siltstones which show little or no cleavage.

The walking stick is 0.9 m long.

The photo of the entire structure is here:
