Earthwatcher's photos with the keyword: guessed by Woodlands1968

Originally uploaded for the Guesswhere UK group. This is a view looking up at the landslide area at the western end of Pinhay Bay, east Devon. The trees are at all sorts of odd angles and some have fallen completely due to the continuing intermittent landslide movements. The top of the landslide scar is seen in this photo: www.ipernity.com/doc/earthwatcher/39024280

Originally uploaded for the Guesswhere UK group. View north west looking towards the B5055 (on the far side of the stone wall running from right to centre). Monyash village is just out of sight beyond the trees on the centre skyline. The valley is asymmetrical in cross-section at this point (and at number of other locations along its length). The steeper and rocky north-facing slope - on the left in this photo contrasts with the more gentle southward facing-slope. This is interpreted as a periglacial effect dating from the last glacial period (the Devensian) when the Peak District was largely free of ice, yet subject to intense cold. The north-facing slope would have been largely in shade for much of the year, remaining frozen. The permafrost on the south-facing slope would have partially melted during the summer months, allowing solifluction/gelifluction processes to transport material into the valley bottom, blurring out the rock features. Lathkill Dale itself is thought to have originated, at least in part, as a tunnel valley: erosion by a sub-glacial meltwater channel during pre-Devensian glaciations when the Peak District was covered by ice.

A nice example of a tight, nearly isoclinal, upright syncline in the Bude Formation (Upper Carboniferous) at Wrangle Point, Crooklets near Bude in Cornwall.

A day on the Marloes peninsula 1 Pembrokeshire, west Wales. Originally uploaded for the Guesswhere UK group. The distant headland is the northern coast of Skomer Island, with the small islet of the Garland Stone just to its right. Wooltack Point is the nearer visible headland and I was standing on the hillside above Haven Point, just west of Martin's Haven.

This is a view west towards Gilman Point from Dolwen Point, near Pendine, Carmarthenshire, west Wales. Beds of Carboniferous Limestone dip gently westwards.

This is the Duckmanton Railway Cutting Site of Special Scientific Interest, near Chesterfield, north-east Derbyshire. The arch structure on the right is a shelter built to preserve and allow access to the the Chavery Coal and its overlying roof mudstones. The same coal seam is visible in the bank at the top of the steps on the left. This was worked (illegally) by desperate miners during the 1984-85 miners' strike. (Chris Darmon, pers. comm.) The railway cutting is a site of international geological importance, as it contains the stratotype section for the Anthracoceras vanderbeckei (Clay Cross) marine band which is the boundary between the Langsettian and Duckmantian Stages of the Carboniferous, informally the junction between the Lower and Middle Coal Measures. Camera viewpoint is approx. SK 4224 7037, looking westwards. The site is managed by the Derbyshire Wildlife Trust and is accessible by permit only. www.derbyshirewildlifetrust.org.uk/reserves/duckmanton-railway-cutting

Originally uploaded for the Guesswhere UK group. This is one of the classic British angular unconformities. Horizontally bedded Carboniferous Limestone unconformably overlying Silurian greywacke siltstones dipping at about 45° This is at Foredale Quarry just south of Horton-in-Ribblesdale, North Yorkshire. Scanned from a Kodachrome transparency.

Originally uploaded for the Guesswhere UK group. It was a grey day, some might say gloomy, yet such colour in the landscape. This lovely meadow is the River Amber valley near the village of Ashover, Derbyshire. The line of hawthornes in the centre of the photo mark the course of the former Ashover Light Railway: www.alrs.org.uk/site/

Originally uploaded for the Guesswhere UK group. A view west from the Lyke Wake Walk route on Howdale Moor near Ravenscar, looking towards Fylingdales Moor, North Yorkshire Moors National Park.

Originally uploaded for the Guesswhere UK group. This is a view from Stoupe Brow down towards the old Peak alum works site near Ravenscar, North Yorkshire. The old alum shale quarries are just out of sight below the heather-clad bank in the foreground.

Originally uploaded for the Guesswehere UK group. This is the hyaloclastite front formed by the Upper Miller's Dale Lava where it originally flowed into the sea, exposed in Litton Mill Railway cutting on the Monsal Trail in the Peak District National Park, Derbyshire.

Originally uploaded for the Guesswhere UK group. This is a section of the old A625 Sheffield to Chapel-en-le-Frith road at the foot of Mam Tor in the Peak District. The road was built across an extensive active landslip area and was in constant need of repair. The photo shows the repetitive layers of successive repairs made to this section. The road was finally closed in 1979. The landslip first formed about 3000 years BP, on an oversteepened slope left after Devensian periglacial period. There is an 80 m high back scar in formed in the Mam Tor Beds. The toe of the landslip is still active today, moving at up to 2 metres per year in places.

This is a view of the plunging syncline in the small islet in Middle Cove, just north of Stackpole Quay, Pembrokeshire. The fold is developed in Carboniferous Limestone, with a plunging axis trending approximately ESE-WNW, dipping easterly. The fold style is mostly concentric, but the 'space problem' in the centre of the fold has been accommodated by small-scale thrusting and crumpling, and additional movement taking place along bedding planes.

This warning sign (as if you would....!) is at Cobbler's Hole, a steep rocky inlet on St Ann's Head in Pembrokeshire. It has almost vertical walls with the sea crashing in and out over 100 feet below. The star attraction of Cobbler's Hole is the splendid anticline and syncline fold couplet in the Devonian-age Milford Haven Group of the Old Red Sandstone rocks.

Originally uploaded for the Guesswhere UK group. This is Patching Pond, near Worthing, Sussex and is a good example of a doline (sinkhole or solution hollow). The bedrock is Chalk, but covered at this location by a thin veneer of solifluction deposits ('Head').

Originally uploaded for the Guesswhere UK group. Calton Hill quarry was worked for basalt (roadstone or railway ballast, I think) but closed quite a number of years ago. The quarry exposed a complex section through a volcanic vent and associated dolerite sill. The columns in centre of the photo are part of the sill, but there are also an extensive series of basalt lavas, tuffs (volcanic ash) and vent agglomerates ( shattered and fragmented rock that has fallen back into the former volcano crater) some of which can be seen in the darker, finer grained material in the upper part of the cliff. The quarry was partly used as a landfill site, but that is now completed, capped and grassed over. The steep grassy slope with thin terraces in the upper left is the front limit of the landfill.
