purple and light-coloured ferruginous shale lying between dolomitic and dark j 
lumpy bands. Further on dirty brown limestone is full of shell fragments, and 
again solid limestone alternates with shaly bands. : 
This gorge is the mo.st profound traversed by the road; on one of the i 
mountains close to the westward, overlooking it, a height is marked of 6,645 feet; j 
and supposing the stream to be 4,200 feet, the section exposed in the steep i 
mountain side may be nearly 2,000 feet in height. The rocks for about a mile 
in the narrow part of this gorge are all of the triassic aspect just now described, 
and they are seen to be contorted in the wildest fashion, a group of hard beds 
showing their edges vertically for some hundreds of feet, and standing as it were 
upon a strong horizontal outcrop below, as well as presenting in other places a 
variety of compressed curves. Leaving the narrow part of the gorge and 
descending into the valley of a small tributary from the east, the Attock slates 
are again expiosed, forming a small denuded inlier, beyond which northwards 
crags of the disturbed triassic-looking limestone reappear. Just beyond this, 
the Dore river bonds to the west, and in its further bank (the left), there is an 
exposure of black Sp)iti shale with fragmentary Ammonites and many Belemnites 
as usual. From this onwards, the road rises high above the right bank of the 
river, and passes along cuttings in much contorted nummulitic limestone, with 
two or three exposrrres of black coaly or car’bouaceous shale, associated with 
ferruginous and quartzite sandstone. Black shales are also seen cropping out 
at the lower part of the limestone cliffs on the ojjposite (southern) side of 
the river. 
As the valley opens and the road enters the little flat of Damtour, lime¬ 
stones of triassic aspect come out from under the nummulitic ones, and form the 
face of the hill east of the village. Beneath these limestones are seen the 
Attock slates with a high easterly dip, and the lowest bed of the limestone series 
above, resting directly upon the slates, is a sandy conglomeratic one enclosing 
fragments of the underlying slate gTOup, as observed in the Sirban mountain 
sections; but it is worth notice that the largely developed masses of red sandy or 
earthy ferruginous beds and greyer silicious dolomites representing the Infra-trias 
group of that adjacent mountain are here absent. 
From Damtour onwards the road passes among and over the deep detrital 
deposits of the Abbottabad plain. 
The mountains to the eastward repeat, with numerous disturbances and 
dislocations, the features of the Sirban mountain section, described in Memoirs 
Geological Survey, Vol. IX, Art. 3. The Spiti shales are locally more largely 
developed, and likcAvise fossiliferous Belemnitti and Ammonite-bQ&ving sandstones, 
which may be a portion of those referred to the Gieumal group. The Infra-trias 
cherty dolomites are largely present in the northern parts of these mountains, 
but appear to be capriciously distributed, sometimes alternating with sub-fossili- 
feroua bands having entirely the triassic aspect, and in places occurring in some 
force before they rather suddenly disajipcar to the southwards. Their connexion 
with the Tanol gi’oup of Hazara is strongly suggested by the sections in the 
northern parts of these liills, and will be refeiTed to in a separate note.
