Fic. 52.—Seracs of the lower cascade of the Krakokta glacier. 
Fic. 53.—View of the lower part of the Krakokta cascade looking northwesterly. 
The dark line which crosses the figure near the center is a jozz¢ terminal moraine, 
formed by the contact of the Krakokta and Tuktoo glaciers, moving from opposite 
directions, the former from the south, the latter from the north. Beyond the moraine 
near the extremity of Tuktoo glacier, a small nunatak is seen at the right of the figure, 
around which the ice is depressed. The larger prominence in the center separates the 
Tuktoo glacier from the Sun glacier. The snow-cap on the heights at the left in the 
distance is the edge of the ice-cap of Prudhoe Land, and is continuous with the main 
ice-cap, which lies to the right.
