The Columbia Glacier in southern Alaska •

Last update: July 13th, 2020 at 9:00 am

Today’s Image of the Day from NASA Earth Observatory features the Columbia Glacier in southern Alaska, which has experienced a long period of rapid retreat followed by a more stable period in recent years. 

Shad O’Neel is a glaciologist at the USGS Alaska Science Center who has been observing the behavior of the Columbia Glacier for many years. 

“The total loss of ice is down substantially,” said O’Neel. “But there is still impressive retreat.”

The glacier has lost more than half of its total thickness and volume since the 1980s. 

This natural color image was captured on June 21, 2019 by the Operational Land Imager on Landsat 8.
