Glacier Turns into a ‘Snow Swamp’

In just four days this summer, miles of snow melted from
Lowell Glacier in Canada. Mauri Pelto, a glaciologist at Nichols College,
called the area of water-saturated snow a “snow swamp.”

These false-color images
show the rapid snow melt in Kluane National Park in the Yukon Territory. The
first image was taken on July 22, 2018, by the European Space Agency’s Sentinel-2;
the next image was acquired on July 26, 2018, by the Landsat 8 satellite.

Ice is shown as light blue, while meltwater is dark blue. On
July 26, the slush covered more than 25 square miles (40 square km).

During those four days, daily temperatures 40 miles (60 km)
northeast of the glacier reached 84 degrees Fahrenheit (29 degrees Celsius) —
much higher than normal for the region in July.
