I9XI] PRESSURES AND CREVASSES AGAIN 59 
dropped from -21 '5° at 11 a,m. to -45"^ at 9 p.m. We 
then made our night camp amongst the pressure ridges 
off the Terror moraine, on snow that felt soft and deep 
enough to be safe in what we believed to be one of the 
hollows [and when we camped after getting into a bunch 
of crevasses and being completely lost, ' At any rate,' 
Bill said, as we camped that night, ' I think we are well 
clear of the pressure.' There were pressure pops all

tank.] 
Thursday^ July 27, 191 1 . — We got away with the 
coming of daylight and found that our suspicions over- 
night had been true. We were right in amongst the

distance between two of them without actually crossing 
any but very insignificant ones. Ahead of us was a safe 
and clear road to the open Barrier to the south, but we 
wanted to go to the S.W. And as the pressure ridges were 
invariably crevassed on the summits we hoped that by 
continuing along this valley we might find some low 
spot where we could cross the ridge on our right, and 
again get on the safer land ice. We, however, found no 
such dip, and after some time decided we must cross 
the ridge on our right [an enormous pressure ridge, 
blotting out the moraine and half Terror, rising like 
a great hill]. In doing so we managed to negotiate 
several rottenly bridged narrow crevasses [both Bill 
and I putting a leg down] and one broad one which we 
only discovered when we were all on it with the sledge, 
and then Bowers dropped suddenly into one and hung
