 branches of the stagnant portion of Hubbard Glacier, to 

 be described on another page. 



Close to the end of Nunatak Glacier were two lateral

Beyond it, a hanging valley, with a small glacier. The heights are hidden by cloud.

That at the north (fig. 31) occupied a trough trending

 about 200 feet high. At the south the cliff ended against
