CONTEMPORARY SEDIMENTARY ENVIRONMENTS ON BAFFIN ISLAND, NWT, CANADA - DEBRIS SLOPE ACCUMULATIONS

Observations are reported of the morphology and processes on debris slopes in Home Bay and northern Cumberland Peninsula regions of east Baffin Island. Accumulations range from debris mantles on bedding plane slopes, through conical and sheet talus, to slopes on which snow avalanche or water flow has modified features. Other features include protalus debris accumulations, and 'talus rock glaciers'. Observations of material delivery and slope stability at Ekalugad Fiord reveal that rockfall is the primary rock delivery mechanism, though dirty snow avalanches are also significant.-from Authors
