Ice-cored drumlins at the surge-type glacier Bruarjokull, Iceland: a transitional-state landform
This paper presents data on a glacial landform that, to Our knowledge, has not previously been described in the literature: the ice-cored drumlin. The study area is the forefield of the surge-type glacier Bruarjokull at the northeastern margin of the Vatnajokull ice cap, Fast Iceland. Based on sedim...
