Nabesna (glacier)
Nabesna glacier against the backdrop of the Wrangel Mountains
Nabesna is a glacier in Alaska in the United States. Its source is in the thick snow cover of the Wrangel Mountains. The length of its main course is 87 km. It is one of the longest extinct glaciers on earth.
The traits of the Nebes were examined in the winter and spring in the years 1994-1996. The results show that the average flow velocity of the glacier during the winter-spring period ranges from 0.3 to 0.7 m per day. It is expected that this speed in the summer is significantly higher.
