Between Cold Moor and Cringle Moor is a large bright red scar on a field.
On closer inspection it appears to be a large amount of burnt shale, very different in colour to the dozens of shale tips in the area.
This could be the remains of an Alum Clamp which was an early stage in the Alum making process. Or it may just have burnt for reasons unknown.
About 50m up the slope there is a recent collapse in the ground, although I cannot tell if this is related.
