with tidal current must be active. The forward flow of 

 the ice tends to narrow the strait, and this constriction, by 

 increasing the speed of the tide, enhances the melting 

 power of the water. The fact that the glacier was able 

 to occupy two-thirds of the width of the fiord indicates 

 that its forward movement was strong.

 of drift-charged ice which extended obliquely down-

The cliff was further diversified by a number of caves 

 at the water's edge, supposed to be the mouths of englacial 

 streams.
