  • Glaciers move due to the ice on the base becoming wet from heat.
  • Muldrow Glacier has not moved this fast since the 1950s.

Muldrow Glacier, a mountain in Denali — south central Alaska — is moving quickly in what is called a glacial surge event.

The surging glacier is moving at a rate between 50 and 100 times faster than normal, according to Denali National Park,Gizmodoreported.
