Alaska Airlines flight seeing

 Every once in a while you get one of these amazing blue sky days in Southeast Alaska. That's when a routine commute turns into amazing flight seeing, and it pays off to consistently book window seats! These pictures are from a flight from Juneau to Anchorage and then back to Fairbanks.

Glacier Bay. The Tlingit name is Sit' Eeti Gheeyi (Bay in the place of glaciers).


Yakutat Glacier. We had a project there a few years ago when all that lake was still covered with ice.

West branch of Yakutat Glacier that has now separated from its tributary. Our models indicate that this glacier will entirely disappear during this century, even without any further warming.

Looking up Russell Fjord to Hubbard Glacier. The huge Mt. Logan is in the background left.

Close-up of the advancing Sit' Tlein (Hubbard) and Sit' Kusa (Turner). The Sit' Kusa enters from the left and is known for its regular and vigorous glacier surges.

The Sit' Tlein (Malaspina) with Malaspina Lake. It looks like the lake has been getting bigger since last year.

Looking across the Sit' Tlein into the tributary Seward Glacier (on the right) and Agassiz Glacier (on the left).

Lig̲aasi Áa (Icy Bay) with Yas'eit'aa Shaa (Mt. St. Elias). The Tyndall Glacier descends from the mountain at over 5,400 m down to Taan Fjord.

A look over the Bagley Icevalley, which is over 1400 m deep. In the background are the Wrangell mountains.

Denali (the Great One) is peaking out of the clouds. To its left is Sultana (The Wife, Mt. Foraker). I think Begguya (The Child, Mt. Hunter) is just peaking out between the two.

IGS meeting on Maritime Glaciers: Excursion to Tracy Arm

 We had a nice meeting of the International Glaciological Society in Juneau. This was my first in-person meeting since the start of the pandemic. It was so good to see old friends and make new connections. During the week, we had a beautiful excursion to Tracy Arm, just South of Juneau. I had not been there since 1996. What an amazing place.

A Black Bear feeding on barnacles. It's amazing how they navigate the steep fjord walls.



The South Sawyer Glacier, which has retreated significantly since I visited it in 1996.


The Sawyer Glacier. It has almost retreated out of the ocean.

This side of the glacier is grounded on a gravel bar now. The gravel provides sufficient resistance for form this beautiful fold in the ice.

... and a beautiful sunset, probably with some help from the forest fires in the interior.
