Opposite Keld on the north are two long glens called West 

 and East Stonesdale, with a ridge of moor between them which 

 attains the Upper Zone. West Stonesdale is a heathery open 

 undulated dale, with but little cliff, and near the head of it at a 

 height of 500 yards above the sea-level is the gritstone colliery 

 of Tanhill. It is a singular situation for a colliery, the edge of 

 a high ridge of hill at a distance of five miles from even the 

 nearest village, and round it upon every side the moorland 

 ridges and peaks. The level which is driven into the hillside 

 is about three-quarters of a mile in length, and the coal is of 

 fair quality. There is a good road from Keld up this dale, 

 which unites with the road which runs between Brough and 

 Reeth at the head of it, and from this colliery the greater part 

 of the coal which is used in the upper extremity of Swaledale is 

 procured. East Stonesdale is a narrower glen, the lower part 

 rocky and sylvan, and a smaller rocky sylvan glen called Hind 

 Hole runs up from the Swale in the direction of Rogan's Seat. 



In travelling by the high road between the head of the Swale 

 and Crook Seat a quarry of the Main Limestone is crossed at an 

 elevation of 550 yards above the sea-level, and as we descend 

 the Main Limestone is seen again at 450 yards in the shape of 

 a .small crag by the Swale side a little above the point where 

 Sleddale Beck falls into the principal river. In the upper part 

 of the Whitsundale glen it attains about the same altitude. At 

 the smelting mill above Keld (iioo feet) we have it on the 

 south side of the stream depressed, by a fault, beneath the sur- 

 face, but in the bed of the river the Underset Limestone shows 



Sept. 1888.
