Recently, I've been able to join this program to add a radar component with the goal of measuring the thickness of the glacier ice. For most glaciers in Alaska, we don't actually know how much ice they contain.
The beauty of airborne science is that it can only happen with good weather. Mountain flying poses so many challenges that we have to wait for conditions to be great. Last week we had five days of beautiful conditions and managed to cover a large part of Alaska's glaciers. Some impressions follow below.

Late fall conditions with only little snow left on many glaciers |

Ultima Thule Lodge: our base of operations |
The ever-amazing Mt. St.Elias from Icy Bay; 5400 m from bottom to top! |

Some Moose enjoying the lush vegetation of coastal Alaska |
We saw much of the snow surface covered in red algae. This is sufficiently darker than the snow to cause additional melting and snow cups. |

The Bagley Icefield with Mt. Logan, arguably the largest mountain in the world. The area over 5000 m asl spans more than 15 km. |
Pothole central on the upper Logan Glacier. These are believed to be left-over and water-filled crevasses and are associated with surges |

The advancing Taku Glacier |
Band-ogives or Forbes bands, an alternating sequence of dark and bright ice forming under ice falls. This one is from the Juneau Ice Field. |

And finally a nice look at beginning fall in interior Alaska. |
