Headline: Tournament Earth 2020: Best Picture Of NASA Earth Observatory Contest - Retreat of the Columbia Glacier

Caption: Recent retreat of the glacier’s West Branch took scientists by surprise. the area of the Main Branch hasn't changed much since 2012, but this part of the glacier is changing in other ways. The field research found a connection between the motion of the Main Branch and the region's tides. The tides are affecting the glacier as much as 12 kilometers (7.5 miles) upstream. The tidal effect only dissipates where the glacier bed rises above sea level and the ice-ocean connection is lost.
