Pym Chair

Earthwatcher has posted:

Pym Chair is a dramatic gritstone tor on the SW flank of the Kinder plateau. Its distinctive notched shape is a prominent skyline feature visible from a considerable distance away.

Ringing Roger foetus-like tor

Earthwatcher has posted:

Ringing Roger is an out-thrusting ridge of gritstone tors overlooking Edale on the south margin of the Kinder plateau.
There is a good path up the ridge with an easy scramble to finish which I think is a much better and quieter route up to the plateau than the slog up Grindsbrook.

Woolpacks 1

Earthwatcher has posted:

The Woolpacks are a group of surreal-looking gritstone tors, shaped by wind and meltwater erosion, on the SW margin of the Kinder plateau. Colloquially known as "Whipsnade" because of their fanciful resemblance to animals (Whipsnade is a zoo in Bedfordshire)

Gigjökull glacier, south Iceland, in September 1988.
It's definitely much smaller now. Evidence of global warming?

Valley bulge folding at Rowlee Bridge, Ashop Valley, Derbyshire

nobody@ipernity.com (Earthwatcher) — Tue, 16 Jan 2007 07:49:25 +0000

Earthwatcher has posted:

The folds are superficial valley-bulge structures in the weak Namurian shales and do not extend more than a few metres into the subsurface. They have formed as a result of the differential loading of the valley sides and valley bottom - the weak valley floor sort of squidges up. This originates mainly from melting of permafrost conditions at the end of the last glacial period around 11,500 years ago.

Continuing movement of the valley sides causes the landslides which periodically disrupt the A57 Snake Pass road nearby on the north flank of the valley.

River Lathkill flowing over the tufa dam at Lathkill Lodge

The River Lathkill in full flood, surging through the tufa dam at Lathkill Lodge, Lathkill Dale, in the White Peak, Derbyshire.

Uprising, carbonate-rich groundwater flowing into the river bed in certain places causes deposition and accumulations of calcareous tufa (a harder and more extensive version of a furred-up kettle), blocking the stream and enabling plants to colonise the river bed. Normally the water flows very slowly here and is sometimes completely dry in the summer.

At high flow times, the river surges through the tufa dam, finding its way through a network of shallow channels, as in the picture.

O'er Bill's Mother's (moody skies over Blea Rigg)

Looking westerly from Silver How towards Lang How, Blea Rigg and the Langdale Pikes.

This entire broad, ill-defined ridge between Great Langdale and Easedale is an absolute delight of miniature rocky peaks, grassy dells and little gems of tarns. A lovely place to spend a lazy, sunny, summer afternoon when the popular summits around about are thronged out with walkers.

On this occasion, it was looking a bit grey and moody. I think Bill's mother must live somewhere over in the the distance.

Cliff erosion 1

Earthwatcher has posted:

Pleistocene river gravels of the proto-Thames form low cliffs on the south coast of Mersea Island, Essex.

This is a site of regional geological importance and is a SSSI.

Active erosion is taking place, with the cliffs receding northwards. Rising sea-levels associated with global warming will exascerbate this effect.
