PLATE CXXL BETWEEN LAND AND GLACIER ICE. 

 From a photograph by R. W. SKELTON (Sk. 301, ^-plate), Dec. 1903. (Map B.) 



At the foot of Knob Head Mountain, in the ice- wall which forms the edge of 

 the glacier, a good deal of englacial rock-debris can be seen ; boulders up to four 

 feet across, ice-scratched and sub-angular, are mixed with numerous small stones 

 and some sand. 



At the spot here shown, two streams of ice meet, and at their junction 

 the englacial matter is forced up 70 feet, and appears as a medial moraine upon 

 the surface.
