south of where the road leaves the salt at the salt quarries, and the 

 usual gray and purple alternations are crossed to where the road descends 

 an incline beneath the fine cliff called ' Yagceshu cumber ' west-by- 

 south from Esar. This is formed of thick gray sandstone with a few 

 dark-gray shale bands below, overlying 150 feet of red clays, the con- 

 trast between the textures of these two thick groups having doubtless 

 favoured the formation of the cliff. Among the sandstones at the lower 

 part of the section here some conglomerate layers as before noticed were 

 again observed. From beneath this cliff the road again ascends to the 

 pass of Soordag (Surdag) through a narrow strike valley where bright 

 red clays predominating among the sandstones give the name to the 

 locality.
