Muldrow Surge Timelapse (May 1 to May 8, 2021)

Denali National Park & Preserve


The advance of the toe of the surging Muldrow Glacier from May 1 to May 8. Watch for movement below the tallest peak in the center of the frame. Moving at 25 meters (65') per day, the glacier moved 175 meters (575') during this week-long period. The white broken ice of the active glacier ice is easy to see, but look carefully at "dead ice" (lower part of the frame) as it get pushed forward by the advancing toe. This dead ice has been slowly melting and stable since 1957's surge.
