=== Locality 2, Holy Well Gill Meltwater Channel ===
  
From the eastern side of Scarth Nick follow the southern edge of the forest eastwards around Limekiln Bank to a good vantage point about 3 km from the road [SE 488 996]. Here the forest ends, giving an uninterrupted view of Scugdale. The valley was once filled by ice. The subsequent meltwater was dammed up by the remaining plug of ice across the mouth of Scugdale which not only faced north but lay in the shadow of the northerly scarp of the Cleveland Hills. The first areas to melt would have been on the south-facing flanks of Live Moor [NZ 504 011]. Stony Ridge on the southwest side probably acted as a solid rock rim to 'Lake Scugdale'. Eventually a notch was eroded at one point [SE 490 992] along this ridge and an impressive glacial drainage channel was cut which now has the name Holy Well Gill. The Gill is dry and eroded into brown, fine-grained, ferruginous sandstone of the mid-Jurassic Ravenscar Group (Crinoid Grit Member). It is some 10 m deep and between 2 and 4 m wide. This channel is the highest recorded in the Cleveland area but its duration as a water-bearing channel was probably short-lived. The water drained into Crabdale and no doubt collected in the Cod Beck Valley, forming a lakelee which eventually drained through the lower channel of Scarth Nick. A small patch of sand and gravel [SE 488 996] on the northern side of Holy Well Gill at an altitude of about 305 m is possibly a remnant of a morainic ridge or reworked glaciofluvial beach deposit marginal to 'Lake Scugdale'.

The Holy Well Gill channel can be followed down into Crabdale to return to the Osmotherley Reservoir car park, or walk back along Stony Ridge and Limekiln Bank to the road.
