dc.description.abstractForkortet: To the East of lake Mjøsa is at Brummundal an isolated outcrop of \"rhombic-feldspar-porphyry\" accompanied by a red or yellowish sandstone quite unique in Norway. The joint occurrence of these exceptional rocks in situ permits of following very closely the direction of boulder transport in the ice ages in this part of the country. The curious fact is disclosed that the blocks are carried much farther West than might be expected from the direction of the rock striae. To the East boulders of these rocks hardly attain a line drawn from the edge of the outcrop S 30-35\u00B0 E of the rock striae: to the West at a distance of 50 km they go some 15 km beyond such a line. It is quite possible that the boulders on Skreia belong to an early period of the ice ages with a more N-S ice movement, the striae on this high mountain generally going in that direction. But as fresh although not much scratched Brumund boulders are to be seen regularly inclosed as well in the superficial deposits at lower elevations, it is not to be doubted that a curious transport must needs have gone on contemporaneously with and at an angle of 30-40\u00B0 with the bottom ice movement as marked off by the striae at the very latest glaciation.
