Stanton Pastures

  • Main open springhead with tufa dome surrounded by rushy vegetation.
  • Measuring water chemistry at top and base of tufa dome.

Limestone Hill

  • Upper part of main waterfall with marginal stands of wild garlic (foreground left and distance right).
  • More heavily shaded rock outcrop (west side of stream) below main waterfall (right) with tufa, Eucladium and localised stands of Palustriella commutata.

Kirksteads Brook

  • Tufa barrages with Pellia endiviifolia (submerged green patches) — wooded section in lower part of brook.
  • Gravel from bed comprised of lose tufa and tufa-encrusted stones.

Trickle Ridge

  • Looking down slope along the back of the impressive tufa dome (known locally as ‘trickle ridge’) towards the river below. Dominant stands of Palustriella commutata.
  • Upper ridge of ‘trickle ridge’ showing the grove that has been cut by local people to accelerate the rate of tufa deposition at the top of the ridge.
  • Seepages below ‘trickle ridge’ (adjoining public footpath of river bank) with Hart’s-tongue Fern and stands of Palustriella commutata.
  • Upper spring head with Wild Garlic and Pendulous Sedge.

Emerald Cave

  • One of several upper springheads with Pendulous Sedge, tufa and stands of Palustriella commutata.
  • Main tufa dome with Palustriella commutata (right).
  • Possible private water supply, although use and ownership is not known.

Booth’s Wood

The moss Cratoneuron filicinum actively associated with tufa formation on a stone within the channel.

The Petrifactions

  • Shaded rock outcrops (left) with tufa, Eucladium and Palustriella commutata looking west (upstream) towards main waterfall (in distance).
  • Strong seepage (SJ9204834781) with adjoining stands of Opposite-leaved Golden-saxifrage and Hard Shield-fern.
