Abstract
The paper deals with glacial striae, roches mountonnees and ice movement in the Faeroe Islands. On an enclosed map, striae and roches moutonnees, partly observed during other field work, are presented together with description of localities. Ice movement is discussed with reference to older works, and it is concluded that the ice reached up to altitudes of more than 700 m and extended far beyond the present coast line. Su6uroy and Sandoy each had a local ice cover, at least during the last glaciation, and in the northern islands the ice radiated out from a principal iceshed running from Vágar to Viðoy.

Highlights
The present paper "Glacial striae, roches moutonnees and ice movement in the Faeroe Islands" is based on observations in·the field during the last fifteen years supplemented by some older observations made during the pre-Quaternary mapping of the islands
On the southern islands striae and roches moutonnees indicate that Su6uroy and Sandoy each had a local ice cover at least during the last glaciation
On the northern islands the undulating main iceshed from Vagar to Vi6oy separated NW flowing ice from SE flowing ice during the maximal glaciation
Summary
The present paper "Glacial striae, roches moutonnees and ice movement in the Faeroe Islands" is based on observations in·the field during the last fifteen years supplemented by some older observations made during the pre-Quaternary mapping of the islands. Helland (1879, 1880) describes some striae and roches moutonnees; his paper is accompanied by a map showing their direction and distribution He shows that the observed roches moutonnees indicate that the ice radiated outwards from the islands, and that the Faeroes had a local glaciation. Hans Rudolphi who visited the Faeroes in 1912 and 1913 refers in his paper "Die F!r8er" (Rudolphi 1913) to glacial striae and roches moutonnees from Streymoy, Sandoy, Eysturoy and Vagar, and he gives some heights for the glaciated outline, which on northern Eysturoy reached almost 600 m. Distinct and well ~eveloped striae and roches moutonnees are mostly found in the lower basalt series, on sill surfaces and in the middle and the upper basalt series where compact and hard lava flows are encountered. Considering these natural variations we have preferred to express the trends with reference to cardinal points corrected to the nearest cardinal, half cardinal or three letter cardinal point
