The Juneau Ice Field is located just north of Alaska’s capital city. The ice field covers 1500 square miles, more than a third larger than Rhode Island, and stretches from Alaska across the border into British Columbia. The ice field is home to over 40 large glaciers and more than 100 smaller glaciers. The Juneau Ice Field has been one of the most studied in the world, with the Juneau Ice Field Research Project being conducted annually since 1946.
One of the most talked about glaciers within the Juneau Ice Field has been Taku Glacier. It has been the last advancing glacier within the ice field. It’s “mass balance” has been in the positive; it has been gaining more snow during the coarse of a year than it has lost in melt.
Taku is the thickest measured glacier in Alaska. It is considered a high elevation glacier, which has helped it maintain the title of an advancing glacier.
That designation has officially come to an end. With the increasingly warm temperatures that Alaska has been experiencing over the past decade plus, the Taku Glacier is now retreating.
When Taku has calved in the past, it has sent icebergs into the Juneau harbor. Massive calving events would not only send icebergs to Juneau, but also into the Inside Passage.
When Columbia Glacier in Prince William Sound started its retreat, sending icebergs into The Sound, the State of Alaska was forced to create an ice-watch program for oil tankers and cruise ships.
Taku Glacier is twice the size of Columbia.
