Yes, it looks very enticing, but the end is pretty undiggable. Dye tests were inconclusive in the '70's, but there are some impenetrable risings in the river to the W to which the water might well go in the end. More promising is Sandholes swallet a few hundred metres to the S, which was also dug during the same period through large boulders to about 8m depth before it ran in very suddenly. Positively tested to Dowel, but slim chance of permission to dig these days, as the same, albeit very nice farmer has filled in and indeed completely obliterated all signs of the equally promising Stoney Low Hole to the NE. Again, contact OCC for advice re. maintaining goodwill in the area.
