One of the most amazing things I get to do as a glaciologist is to help survey many or Alaska's glaciers from the air, as part of NASA's Operation IceBridge. This spring we have a big program and we started at the very southern end of the state: The Stikine Ice Field. Below are some impressions.
We based our flights out of Petersburg, Alaska; one of the most picturesque places in the state. In the background, the ice field with its most prominent mountain, the Devil's Thumb, is recognizable.
The best-known glacier of the ice field is LeConte Glacier, the southernmost tidewater glacier in the northern hemisphere:
Adjacent to LeConte Glacier is Baird Glacier. Until last year, it was a land-terminating glacier. But then a big subglacial flood floated the terminus and now the glacier ends in a lake. It looks like it might be retreating for a while.
On the way home we passed the Juneau Ice Field. Here is a nice shot of the Hole-In-The-Wall Glacier (on the right) and Taku Glacier (on the left). Both are advancing glaciers. The Hole-In-The-Wall Glacier didn't even exist 150 years ago, it only formed when the Taku Glacier readvanced and spilled over.
