- Description
- This paper considers the role of structural glaciology in debris entrainment, transport and
deposition at Haut Glacier d’Arolla, a temperate valley glacier in Valais, Switzerland. Sedimentological
descriptions and clast analysis have been used to identify relationships between ice structure and debris
transport. Relationships identified are (1) debris associated with crevasse traces, (2) the folding of
rockfall material incorporated within primary stratification to form medial moraines and (3) dirt cones
and englacial debris layers associated with reactivated crevasse traces. A conceptual model is
introduced to summarize the manner in which ice structures at Haut Glacier d’Arolla control
entrainment and deposition of debris.
