Glacial striae
Skálavík.
Because of dense vegetation cover the bedrock is sparsely
exposed in the valley at Skálavík. Near the stream Stórá, at
the western end of the cultivated area, a rock exposure indi-
cates ice movement towards ENE (site 16). Where the bedrock
is exposed on the slopes the exposures are rather weathered.
On the north slopes of HeiSafjall some roches moutonnees can
be seen. They indicate ice movement towards NE (sites 17 and
18). Immediately west of the cultivated area on the north side
of Stórá several NE-SW elongated hillocks are seen.
Húsavík.
The valley at Húsavík is almost entirely cultivated, only
the western part is glaciated. Bedrock appears as roches mou-
tonnees. Very fine examples indicating movement towards SE
are found at Takmýrar (site 19). Roches moutonnees at site 20
indicate direction of glacier movement towards SE and SSE.
Dalur.
The little inlet at the settlement of Dalur on the east coast
continues westward as a small valley. The valley head is acute
and the slopes are steep. No rock exposures can be seen in the
valley floor and those on the slopes are highly weathered. On
the northern slope near the valley head roches moutonnees
indicate ice movement towards ESE (site 39).
Conclusion.
The striae, roches moutonnees and the icesheds in the valleys
point to the fact that the ice cap on Sandoy like that on
SuSuroy (Jørgensen & Rasmussen 1977) radiated from the pre-
sent land area during the last glaciation. On the east side of
Sandoy the ice direction varies from NNW (Skopun) to SE
(Dalur). At the western side the direction is westerly at the
valley north of Skarvanes and at Søltuvík. East of Salthøvdi
it is SE, but at Sandsvágur the direction was locally changed
