(Bl) was taken at 5.1 m water depth from the centre
of the lake.
Lake Hraunsvatn (42 m a.s.l., 0.48 km2, 66°05’N,
20°10’W)
The lake occupies an elongated depression in a
rocky plateau landscape. The western slope is very
steep, and the lake has three small inflows. The largest
one (c. 0.5 m wide) enters at the southem end and part-
ly drains two smaller lakes on the plateau to the south-
west. The outflow over a till threshold is about 2 m
wide and situated at the northern end of the lake. A
beach ridge has been built up to a level of c. 45 m a.s.l
close to the eastem lake shore. The shores are mostly
steep with boulders, and the surroundings are domi-
nated by dwarf-shrub vegetation. The lake has two
small islands in its centre, and the core was retrieved
from the southem basin at 0.9 m water depth.
Lake Geitakarlsvötn (26 m a.s.l., 0.24 km2,
66°05’N, 20°16’W)
The lake basin is bordered by relatively steep
slopes to the west and south, and to the west there is a
rocky plateau, reaching 100 m a.s.l. The lake has two
inflows, the larger of which is about 6 m wide and
drains a relatively large system of lakes to the south.
The lake is separated from a much smaller adjacent
lake by a raised beach ridge, and the outflow over the
gravelly threshold is c. 3 m wide. Lake shores are
mostly steep with cobbles. Plant cover is less continu-
ous in this coastal area, and dwarf shrubs are less
dominant compared to the sites described previously.
The core was taken in the northem part of the lake at
1.5 m water depth.
Lake Kollusátursvatn (22 m a.s.l., 0.51 km2,
66°05’N, 20°08’W; Fig. 3)
The lake is located in a relatively flat coastal area.
