...the Aorounga impact crater, with a diameter of about 17 kilometers (10.5 miles). The original crater was buried by sediments, which were then partially eroded to reveal the current ring-like appearance. The dark streaks are deposits of windblown sand that migrate along valleys cut by thousands of years of wind erosion.

The corner of Kahiltna Glacier can be seen on the map link, but is not present in the thumbnail.
The thumbnail does show Lacuna, Yentna, and Dall Glaciers in the Southern half, and the Chedotnothla(?) Glacier in the Northern half.
