Abstract

Reichenkar rock glacier, situated in the western Stubai Alps (Tyrol, Austria) is a 1400 m long, tongue‐shaped, ice‐cored rock glacier that has developed from a debris‐covered glacier. The snout is advancing over permafrost‐free terrain with present flow velocities of >2 m/a. Basal sliding seems to be an important mechanism to explain such high velocities. Long‐term temperature measurements in the debris mantle at different sites and at different depths show that the heat budget of the debris mantle is complex and strongly influenced by local weather conditions and by frozen material below. On the rock glacier basal snow temperatures (BTS) from late January until April were 2–3°C colder than on permafrost‐free ground outside the rock glacier. Copyright © 2000 John Wiley & Sons, Ltd. Le glacier rocheux de Reichenkar, localisé dans les Alpes Occidentales Stubai (Tyrol, Autriche), est un glacier rocheux long de 1400 m, en forme de langue, avec un noyau de glace. Ce glacier rocheux s'est développé à partir d'un glacier couvert de débris. Son extrémité avance sur un terrain sans pergélisol avec une vitesse actuelle supérieure à 2 m par an. Un glissement de la base paraît être un mécanisme important pour expliquer cette avancée rapide. Des mesures de température à long terme en différents endroits et à différentes profondeurs dans le manteau de débris montrent que le budget thermique du manteau est complexe et fortement influencé par les conditions climatiques locales et par les matériaux gelés inférieurs. Sur le glacier rocheux, le températures à la base de la neige (BTS) depuis fin janvier jusqu'en avril, étaient 2 à 3°C plus froides que, en dehors due glacier rocheux, sur le sol sans pergélisol.
