Abstract

Variation in the magnetic till fabric around one large boulder and three small ones suggests that pressure melting of the debris-laden basal ice on the upstream side of the boulder caused the release of till-water slurry, some of which flowed around the boulders, filling in surface irregularities on the boulders and in the area behind them. The flow of the till slurry around the boulders caused alignment of the clasts in the till adjacent to the boulders.
