Don't know. There were/are plenty of glaciers in that vicinity. But
it doesn't sound like it. Recorded a glacier in the Yakutat area
about 10 years ago (the Hubbard). Dropped a hydrophone down a
crevasse a couple of miles walk from the leading edge and recorded
the low freq mvt of the entire mass over the ground. Got stuff well
into the infrasound region (from bet. 5 and 12 Hz) but it was pretty
much contained within the body of the mass and did not project much
beyond. We were camped for a week directly across from the glacier
about 3/4 mile away and never heard anything but the calving booms
and crashes. None of the continuous rumble I've experienced a couple
of times in AK.
