Surface Lowering of Ice-Cored Moraine by Wandering Lakes

Abstract Lake wander is described as a new mechanism for surface lowering of ice-cored moraines. Evidence is provided from Flanders Moraine, Vestfold Hills, Antarctica (lat. 68° 38’ S., long. 78° 12’ E.). Lakes wander when steep ice scarps retreat due to collapse and melt. Rates of wander are c. 1.3...

Description
Summary:Abstract Lake wander is described as a new mechanism for surface lowering of ice-cored moraines. Evidence is provided from Flanders Moraine, Vestfold Hills, Antarctica (lat. 68° 38’ S., long. 78° 12’ E.). Lakes wander when steep ice scarps retreat due to collapse and melt. Rates of wander are c. 1.3 m year −1 . Rates of lowering due to lake wander on Flanders Moraine are c. 0.05 m year −1 , which is comparable to rates from elsewhere attributed to different processes.
