PHYSICAL GEOGRAPHY 
the west is about 300 feet above the sea : Dufton is 585 feet high, the 
Penine escarpments are from 1500 to 2300 feet. 
Mickle fell; the highest summit in Yorkshire, is capped in the 
eastern part with a small patch of grits, and on the western part a more 
considerable mass appears and rises to nearly 2600 feet above the sea. 
The height of the main limestone is not less than 25331 feet. This may 
be taken as the maximum height of that rock in the whole region round 
the head waters of the Tees : in Dun fell it is 2526 feet, in Scordale 
head 2437 feet, head of Knockoregill 2200 feet, surface of the Whin sill 
at Knockoregill above 1800 feet, at the Bridge of Caldron snout 1489 
feet, at the High force 1000 feet. 
Between JLunedale and the vale of Greta is the great depression 
south of the Lunedale fault — its highest points are on the Penine chain 
under 2000 feet ; Brough at the foot of Stainmoor is 587 feet ; the 
escarpment from 900 to 1300 feet. 
Goldshorough, crowned with the middle or Arkendale millstone 
grit, is 1360 feet above the sea; at Howbeck head, near it, limestone 
and coal occur 1212 feet in height. Partington moors, on the shale 
series below the grit of Goldsborough, Cragg, and Cat castle, are about 
1165 feet, and Partington hall on the same strata 735 feet. 
Stainmoor, at the summit of the great road (in the limestone and 
coal series above main limestone) is 1448 feet high ; the hills crowned 
by the middle grit towards the north rise 300 or 400 feet higher. 
South of it is the wide hollow of Greta dale, and eastward the road 
descends by Stainmoor inn 1262 feet, to Bowes (on main limestone) 
942 feet, and Boldron hill (on the same rock) 883 feet, to Greta bridge 
(on strata below it) 441 feet. About 60 feet lower is the junction of 
the Tees and Greta. 
Between the Greta and Arkendale , the southward rise of the strata 
is not insensible, and the hills resume somewhat of their importance.
