66 A SECTION OF THE CLIFFS NEAR NEWBIGGIN 



In Pre-Glacial, or early Glacial times, the ancient cliff would 

 be the northern boundary of a cove or bay in which fragments 

 of local rocks were rolled and deposited ; sea-worn material 

 from distant places, carried by currents and hurled by the 

 waves, added to the accumulation. A similar deposit is now 

 being formed at the base of " Hawk's Cliff," where sub- 

 angular material, together with rounded sea-worn boulders, is 

 heaped up. A more extensive accumulation may be seen at 

 the mouth of the Wansbeck, but there the material is in- 

 variably rounded and water-worn.
