Juneau Icefield

The Juneau Icefield is an ice field located just north of Juneau, Alaska, continuing north through the border with British Columbia,[1] extending through an area of 3,900 square kilometres (1,500 sq mi) in the Coast Range ranging 140 km (87 mi) north to south and 75 km (47 mi) east to west.

The Icefield serves as a tourist attraction with many travellers flown in by helicopter for quick walks on the 240-to-1,400-metre (790 to 4,590 ft) deep ice and the massive, awe-inspiring moist crevasses.

On the west side of the icefield, from 1946-2009, the terminus of the Mendenhall Glacier has retreated over 700 metres (0.43 mi).

In 1948, the Taku Fjord had been completely filled in with glacial sediment and the glacier no longer calved.

From 1987–2009, the glacier has had a slightly negative mass balance, not enough to end the advance, but if it continues will soon slow it.
