Today’s Image of the Day from NASA Earth Observatory features Glacier Bay in southeast Alaska.

The false-color photograph makes it easier to distinguish between areas of ice, rock, and vegetation.

The ice in Glacier Bay has retreated by about 60 miles since the last time it reached its maximum extent in 1750.

“Recent retreat has been influenced by rapidly warming air and water temperatures,” said Andrew Bliss, a glaciologist with the National Park Service. 

“In the East Arm, all of the glaciers are retreating; in the West Arm, a few glaciers are stable or advancing slightly.”

The photo was captured on September 17, 2019 by Landsat 8.
