A band of limestone runs from Cracoe (a few miles north of Skipton) in a north-easterly direction towards the River Wharfe. This band forms an anticlinal; for along its north-western flank the limestone is seen to dip north-westward beneath beds of shale, which have a similar dip; and on its south-eastern flank the limestone dips south-eastward under the shales and grits of Thorpe Fell, the top of the rock running from Butter Haw nearly along Thorpe Lane towards the northern end of Elbolton. In several places the top of the limestone is brecciated, and the overlying Bowland Shale contains fragments of limestone. Although the general structure of the country is thus sufficiently plain, the details of the limestone are not easily made out. This rock forms five conspicuous hills, more or less conical, which stand up abruptly from the general level of the ground at the foot of the gritstone fell. Their names in order, beginning at the south-west and going round by north-east to east, are Skelterton, Butter Haw, Stebden Hill, Elbolton, and Keal Hill. They are all formed of massive limestone. The beds on Skelterton have an easterly dip, and owing to rolls the top of the limestone runs in a curvilinear fashion to Butter Haw, which forms an anticlinal, and thence nearly along Thorpe Lane towards the northern end of Elbolton, leaving Stebden ]=Jill apparently as an island. On the north side of the last-named hill I found beds dipping north-westward at 40°, but no satisfactory dip
