Fig. 3. Fluvioglacial sediments
in the Vatnsskard-Saemundar-
hlíd area. The southernmost
part is a remnant of a medial
moraine, but north of the farm
Fjall the moraine transforms
into a kame terrace. Some large
eskers are situated to the north
of the terrace. Inside the areas
covered with fluvioglacial sedi-
ments contours are shown with
broken lines. Key: 1. Eskers, 2.
Mounds, 3. Fluvioglacial sedi-
ments covered with bog, 4. Ket-
tles, 5. Lake in a kettle, 6. Inner
limit of a kame terrace, 7. Ter-
races, 8. Dry meltwater chan-
nels, 9. Lateral channels, 10.

Mynd 3. Jökulárset í Vatnsskarði
og Sœmundarhlíð. Syðsti hlutinn er
leifar urðarrana en við bœinn Fjall
tekur við jaðarhjalli. Nyrst eru svo
nokkrir stórir malarásar. Hœðarlínur
eru sýndar með brotnum línum á
svœðum sem þakin eru jökulárseti.

areas are covered by ablation till. In the
mouth of the Djúpidalur valley the deposits
consist entirely of ablation till and no eskers
or fluvioglacial material are observed. On
Hlídarfjall, however, the eskers consist of
fluvioglacial gravel with a mantle of ablation
till. This difference must be due to different
meltwater supply on the surface of the glacier.
