ABSTRACTSnow avalanche impact landforms have been found at many localities in Troms, North Norway. Three morphological varieties occur: a) avalanche impacttongues—tongue-shaped debris accumulations on the distal banks of streams, b) avalanche impactpits—water-filled depressions having a distal tongue-shaped accumulation, c) avalanche impactpools—submerged depressions occurring in larger water bodies and bounded distally by a debris ridge. The features have formed by the cumulative effect of repeated snow avalanche impact whereby debris is ejected from the impact area and deposited distally.
