This crushing and theimperfect cleavage are, no doubt, due to subsequent the deposit is not a crush-breccia, and the boulders are foreignto the locality. The general aspect of the deposit is strikingly likethat which a moraine would probably adopt if solidified, uptilted,and subjected to extreme pressure. The age of the deposit is pro-bably the same as that of the old glacial conglomerate on theYaranger Fiord described by Eeusch and Strahan.
