Abstract
The geomorphic activity on subalpine avalanche paths is examined in the context of past and present climageomorphic regimes. Evidence of change in meso-scale landforms, sediment yield, responding soil development, and microscale sediment cascades are examined using techniques of repeat photography, water quality analysis, soil description, and dendrogeomorphology. Avalanche paths are geomorphically inactive. Neither their form nor the position of distinctive clasts are changing; drainage streams are typically devoid of sediment; soil horizons do not reveal colluvial transport; and tree-tip mounds account for only minor amounts of denudation. The distinct topographic form of subalpine avalanche paths must be due to activity during earlier, possibly paraglacial, periods of the Holocene.
