Description :
This study extends the understanding of the chemical weathering of surficial debris in alpine cirques to that operating in snowpatch hollows on valley sides. Clay mineralogy within the pits exhibits a widespread and distinct change at a depth of 15-20 cm. Spatial variations in eolian additions and meltwater produce complex patterns in chemical weathering of fines beneath large snow patches, although the nature of clay-mineral change is typical of humid, temperate, mid-latitude environments.
