Yakutat Glacier again

In early July we headed back to Yakutat Glacier to maintain GPS instruments and do some more radar. The lower few kilometers of the glacier are about to break apart into the lake and several large ice bergs have already become loose.

Here is Joanna dragging a radar sled over the ice
Icebergs are always interesting, as they came in all sorts of shapes and sizes. Here is one with a large circular conduit from a former englacial water channel.

On the way back to Fairbanks we flew across Icy Bay, an impressive bay north of Yakutat. The glaciers there have all retreated to the end of the bay and drop very rapidly from the high mountains to the ocean. The terrain rises very rapidly from sea level all the way to the top of St. Elias at 5489 m (18008 ft) above sea level over a distance of only about 30 km; surely some of the most amazing topography on the planet.
