ABSTRACTWinter avalanches are of widespread occurrence in Scotland, and yet on many slopes where they are frequent they do not produce the distinctive landforms described by workers in other areas. This paper describes some small-scale features which do occur and which indicate the action of avalanches. These include perched boulders, lichen patches, boulder holes and scratch marks. The occurrence of these features in several locations suggest that they may be widespread indicators of avalanche activity. As such they may be more useful than other indications such as slope angle or sorting, which do not form unequivocal evidence in marginal areas.
