The open gap which interrupts the Brabazon Range midway in its 
course is partially filled by the broad Yakutat Glacier. This is 
merely a lobe descending from the interior ice-fields, not an alpine 
glacier of the type illustrated by the Moser and Miller lobes: The 
descent of the Yakutat Glacier is gradual throughout, but at several 
places there are steeper declivities, more crevassed, which approach 
the character of ice-falls. The length of the glacier after it leaves 
the parent ice-field appears to be about 12 miles. Its average width is

of a capacious cirque. 
3-4 miles, but toward the end it becomes ragged in outline, and the 
width decreases to 24 and finally to 14 miles. So far as observed, the 
surface of the ice is badly crevassed, especially near the terminus. There 
the ice is broken by great cracks, some of which admit the water of 
the lake far back into the glacier. Four or 5 miles back from the end, 
and especially along the margins of the glacier, there are, however, 
certain stretches which are moderately smooth and may be traversed 
without notable difficulty. The Yakutat Glacier lacks the prominent
