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.

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.

The River Lathkill and one of the weirs on the reach near Over Haddon. Water appears to be flowing through fissures in the limestone river bed beneath the weir and emerging downstream as a zone of bubbling and upwelling, visible in the the centre of the photo.

This is the River Lathkill near the village of Over Haddon, Derbyshire, England. The mini-cascades are an artificial device to create pools for trout fishing.
