1 6 baker's north YORKSHIRE. 



East of Lovely Seat it attains t,6oo feet in Satron Hangers, and 

 from thence sinks eastward to 800 feet in Downholme Moor. 



A few miles from the head of Swaledale the valley divides 

 into two, and the two branches rejoin each other at Muker. A 

 fine ridge of hill which bears the name of Kisdon is thus 

 insulated, and here the Yoredale Rocks may be well seen, the 

 Main limestone forming the summit of the mass at its southern 

 extremity, but having a cap of Millstone Grit over it at the 

 north end of the ridge, which reaches an elevation of 1,643 ^'^^t. 

 The tract between the Swale and the Greta is a rich and long 

 worked lead-mining country, with many dislocations. In Nine 

 Standards the Main limestone attains about 1,700 feet. Ascend- 

 ing Water Crag by way of Stonesdale, we have the Underset 

 limestone at an elevation of 300 feet above Muker and 1,150 

 feet above the sea-level ; above it about 60 feet of non-calcareous 

 interpolation, 80 feet of Main limestone, and between this and 

 the hill summit in this direction nearly 900 feet of the beds of 

 the Millstone Grit series ; but on the eastern or Arkengarth- 

 dale* side of the same hill the Main limestone is nearly 100 feet 

 higher, its upper surface in Punchard's Gill being 1,360 feet in 

 elevation, with the base of the Underset limestone 190 feet 

 below it, and 230 feet more of the lower beds before we reach 

 the bed of the stream. Towards the south-east the Main lime- 

 stone reaches 1,600 feet in the angle between Arkengarthdale 

 and Swaledale above Reeth. Along the line of the former dale, 

 which runs from the north-west towards the south-east, a fault 

 depresses the beds in a north-eastern direction, and in Fre- 

 mington edge we have the Main limestone at 1,150 feet, and 

 the Middle limestone at 200 feet above the river. From this 

 point through the moorlands eastward to the Castle Hill at 

 Richmond, a distance of eight miles, the Main limestone sinks 

 gradually to 450 feet. 



* Misprinted Argengarthdale in Ramsay's map ; where also read 

 Ampleforth for Appleforth (S.W. of Helmsley) and Flaxton for Flexton 

 (N.E. of York); also Heworth, a suburb of York, is misplaced four miles 

 to the east. Arkengarthdale is sometimes abbreviated into Arkendale.
