Glacial striae
59
Høgadalsá opens into the fiord, both roches moutonnees, SE, and
striae, NW-SE, can be seen (site 70). Around Kaldbaksnes striae
run E-W and ESE-WNW (sites 68, 69). On the east coast north of
Kaldbaksnes glacial striae running NNW-SSE were observed at
site 91.
The central area.
The terrain between Tórshavn and Kaldbaksfjørður is uneven,
marked by NW-SE trending topographic features such as water-
courses, gullies and elongated hillocks. From the coastal slopes the
terrain rises westward to the hills Gellingarklettur (343 m a. s. 1.)
and Húsareyn (347 m a. s. 1.) which are aligned in north-west
south-easterly direction.
The hillocks are clearly glaciated, but those in the interior of the
area lack for the most part the typical shape of roches moutonnees.
Larger areas covered with gravel produced by weathering can be
seen in several places.
On the south coast of KaldbaksfjørSur the striae and roches
moutonnees are aligned according to the winding course of the fiord:
north-west of the village Sund they indicate ice movement toward
ESE (sites 80, 85), and at Sund, toward E (sites 65, 78). Immediately
before the coast line at the mouth of KaldbaksfjørSur turns toward
south-east, the lee sides of the roches moutonnees face E and ESE
(site 76), farther south the direction is ESE (sites 7—10), and at
Hvítanes SE (sites 11—13). (Fig. 1, 2).
East of Sund (sites 75, 77, 79) heavily glaciated gullies can be
seen in vertical section through the basalt benches on the north-west
slope. At site 75 roches moutonnees show ice movement toward SE.
Site 77 comprises a gully through three glaciated basalt benches
(roches moutonnees) showing ice movement toward SE and ESE.
At site 79 roches moutonnees run SE and striae ESE-WNW. Be-
tween Hvítanes and Hoyvík (site 14) striae running NNW-SSE
were observed, and at Hoyvík (sites 24, 25) roches moutonnees
indicate that the ice here moved toward SSE.
Glacial striae and roches moutonnees within the boundaries of
the oldest part of the capital Tórshavn have been observed by
