This Alaskan Glacier is Moving 100 Times Faster Than Normal

K2 Aviation runs scenic flights around Denali, America’s highest point at 20,310 feet, and transports aspiring summiters to basecamp. On a routine flight in early March this year, pilot Chris Palm noticed something unusual on the flanks of the mountain. The normally uniform Muldrow Glacier was sliced and diced with exceptionally large cracks and crevasses. Not in one spot, but everywhere. The glacier looked like it was falling apart. The Muldrow is a 39-mile long glacier that starts high on the northeastern slope of Denali and flows into the McKinley River. It’s one of four main routes to the summit (the others are the West Buttress, West Rib, and Cassin Ridge), and for the last 60 years, it has flowed downhill at a rate of 3 to 11 inches per day. It’s now moving at a blistering pace (for a glacier) of 30 to 60 feet per day, or up to 100 times faster than usual.

Denali glacier speeding downhill By Morgan Krakow, Anchorage Daily News Published: April 20, 2021, 6:02am Share: The view from Eielson visitor center in Denali National Park. (Jeffrey Kreulen/Dreamstime) ANCHORAGE, Alaska A Denali glacier suddenly moving at a speedier clip is intriguing scientists, increasing the risk of nearby flooding and potentially closing off some climbing routes on the mountain this season. Muldrow Glacier which begins on Denali’s northeastern slope and flows to form the McKinley River is experiencing a geologic phenomenon: a surge event. The glacier, which usually moves at an average or slow speed, is now jagged and covered with crevasses as it stretches and moves 50 to 100 times faster than normal, according to the National Park Service.

This Glacier in Alaska Is Moving 100 Times Faster Than Normal

The Muldrow Glacier, on the north side of Mount Denali, is undergoing a rare surge.

Alaskan glacier has started moving 50 to 100 times faster than normal, scientists say

feed to stay on top of the news. Experts aren’t sure what causes the surge, but they suspect this particular one isn’t related to climate change. Still, a warming world is causing many of the world’s glaciers to recede and has been implicated in some surge events. The bottom base of the ice creates a lubricant for the glacier to tile or move. “The whole thing is flowing very slowly, and then suddenly it accelerates, and that can cause the glacier at higher elevations to thin, and then the ice slumps down to lower elevations,” Kingslake explained. “Then that happens, and it slows back down, and the material at lower elevations starts to melt, and the ice near the top thickens, and the whole thing repeats. It’s doing, like, a see-saw thing.”
