PermaFrance Laurichard rock glacier - France

An active rock glacier in the French Alps, at the climatic boundary between Mediterranean and Oceanic climatic zones, near the Col du Lautaret (45°N). Located between 2650 and 2450 m asl, this ice-rich permafrost landforms, typical of high mountain periglacial environments, is studied since the late 70' and has the longest series of monitoring. Its displacements are measured using geodetic methods (total station, GPS, terrestrial LiDAR and photogrammetry). Monitoring of the Laurichard rock glacier aims at understanding the responses of mountain permafrost to Climate and Global change.
