This time-lapse video shows the advance of the toe of the Muldrow Glacier during the 2021 surge from May 8 to July 1. During the 54 days in this time-lapse the active toe front advanced more than 1 kilometer (0.6 miles). Digital elevation models developed from air-photo flights indicated that the toe of the glacier rose about 200 m (650 feet) over the summer of 2021. The growth of the toe and rising height of the glacier are visible throughout the video.
