40 WYNNE : GEOLOGY OF THE SALT HANGE IN THE PUNJAB. 



Beyond the narrow part the range expands into the Tredian hills, 



reaching to within a few miles of the Indus, and 

 Tredian hills. , .-,^0^-1 o/iiT 



having a width 01 8 miles near bwas, but dim- 

 inishing as the river is approached. They have an average height of 

 3,087 feet, and their highest point is reached at Tredian itself, 3,477 feet. 



At the debouchure of the Indus upon the plains the Salt Range may 



be said in most senses to disappear for a space in 

 Disappearance of the _ p • o -y 



range proper at the In- a way difficult to account for Satisfactorily, a few 

 small and disconnected hills only remaining to 

 represent it. The chief of these detached portions, formed of the most 

 perishable materials of the whole series of the range, is the salt hill of 

 Mari, consisting of red marl, gypsum, and rock salt, and having an 

 altitude close to the river's bank of 1,931 feet.^ The geological and 

 physical relations of the Salt Range re-appear in some measure Trans- 

 Indus beyond the limits of this district. 



As one continued massive feature the range may be said to com- 

 mence at its eastern plateau, where the high 

 ground from Jalalpur, rising gradually from the 

 Btinhar river, meets and almost joins the Diljaba portion of the Bakrala 

 ridge : from hence westward nearly to the summit at Sakesar, high 

 plateaux form its crest. These may be called the Eastern plateau, the 

 Dandot plateau, the Kahun, Malot, Niirpur, and S6n plateaux. 



The " Eastern plateau " extends westward to Bid, a distance of nearly 

 sixteen miles, with a width of from one to eight 

 miles and heights of from 2,100 to 3,800 feet, the 

 width of the whole range here being from 7 to 10 miles. The surface 

 undulates, being frequently of bare rock, worn waist-deep into closely 

 adjoining furrows. The plateau is much indented by the heads of valleys 

 along its south-eastern side, and bordered in the opposite direction by
