Hubbard Glacier
Photos
August 14, 2002
On August 14,
2002, pressure from the water rising in Russell Lake, fed by heavy rains,
eroded and then burst the dam that had formed between the advancing Hubbard
Glacier and the rocky bluff of Gilbert Point. In less than 30 hours, the
water level in the 70-square-mile lake dropped 45 feet, from 61 feet above
mean low tide to 16 feet above mean low tide. The surge of water created
spectacular effects and scoured the channel clean. By high tide on August
15, water was moving relatively serenely back into Russell Fjord with
the tide. The glacier face towers about 300 feet above the surface of
the water, and the channel between ice and rock is estimated to be about
1000 feet at its widest point. The following photos were taken at about
7 p.m. August 14, roughly midway through the emptying process. They start
on the Russell Fjord side of the channel and proceed over Disenchantment
Bay. All were taken by Mary McMullin. Click on each photo to bring up
a larger version of the image.
The following photos were taken on August 15 and show the tide running
from Disenchantment Bay into Russell Fjord at a much slower pace than
it left the day before. The channel width is estimated at an average of
about 900 feet. The last photo shows the water line of the former lake.
All were taken by the National Park Service.
