14 Glacial striae verging direction of ice movements from NNE at the most easterly site (site 31) to N (site 32), NNW (site 33) and NW (site 34). Farther west in the ridge-and-lake area the move- ment of the glaciers has clearly been towards NNW (sites 35, 36 and 37). This is indicated not only by the stoss and lee sides of the roches moutonnees, but also by the landscape fea- tures at a larger scale i. e. the shape of the NNW-SSE trending ridges. Norðara Hálsavatn and Heimara Hálsavatn. NorSara and Heimara Hálsavatn are two small lakes about 500 m long and 100 m broad situated in the northern part of the NNW-SSE trending valley from Skopun to Sandsvágur. Norðara Hálsavatn is bordered to the north by a slightly ele- vated area, which is the highest area in the valley, about 130 m a. s. 1. At the northern end of Norðara Hálsavatn the roches mou- tonnees indicate ice movement towards N and NNW (sites 7 and 8). The terrain is covered with vegetation and many blocks are strewn on the surface. Not until the southern end of Heimara Hálsavatn can bedrock exposures be seen (site 9). Here again glacier movement is towards N, but immediately to the south of this locality roches moutonnees are found indi- cating ice movement towards SE (site 10). Thus the iceshed is apparently to be found just south of Heimara Hálsavatn. The present watershed is located at site 7 at the northern end of Norðara Hálsavatn. Søltuvík. Søltuvík is a little inlet on the west coast of Sandoy. From here an area of low land runs in a south-easterly direction. The exposed bedrock is glaciated. Roches moutonnees indicating ice movement towards SW were observed at the western end of Hvíthamar (site 13) and north of the bay (site 40), coinci- dent with Geikie’s observations (Geikie 1880). In the valley head south of Søltuvík the roches moutonnees indicate ice movement in NNW direction (site 41).
