3.2 Period 2: Stabilization (November 2004-2010)
By November 2004, the terminus of Crane Glacier had ceased its retreat
10.05 km upstream of its November 2002 terminus. The terminus remained
stationary for the following six years, with a terminal cliff and
terminus position that fluctuated by less than 500 m during that period.
One of two conditions must have been met: either (a) the calving rate
fell to the glacier speed at that location, or (b) this position defined
the threshold for cliff failure, with a calving rate much higher than
the ice velocity downstream and a cliff calving rate of 0 km/a upstream.
Meanwhile, the system adjusted to the large mass-disequilibrium by
thinning upstream (Figure S5), reducing the driving stress and slowing
its flow speed. This period saw an average thickness change of -16.3 m/a
(0-15 km from the terminus) and a maximum velocity change of
approximately -237.5 m/a2, which occurred between
2005-2007 (0-20 km from the terminus).
