This study explored the impact of landslides on their topography using a landscape evolution model called ‘Hyland’, which enables long-term topographical analysis. Our finding reveal that landslides are concentrated at two specific elevations over time and predominantly affect the highest and steepest slopes, particularly along ridges and crests. This study is part of the large question about the origin of the erosion acceleration during the Quaternary.

This study, using ESR, OSL, and LA-ICPMS trace element analyses, reveals significant relationships between quartz OSL/ESR sensitivities and bedrock characteristics. Trace element compositions appear to influence the OSL and ESR-Ti sensitivities, the last being weak in quartz extracted from metamorphic or deformed rocks. Pressure may take a part in OSL/ESR-Ti sensitivities variability while ESR Al intensities could be linked to initial fluid composition and crystallization conditions

We apply quartz ³He paleothermometry along two deglaciation profiles in the European Alps to reconstruct temperature evolution since the Last Glacial Maximum. We observe a ³He thermal signal clearly colder than today in all bedrock surface samples exposed prior the Holocene. Current uncertainties in ³He diffusion kinetics do not permit distinguishing if this signal results from Late Pleistocene ambient temperature changes or from recent ground temperature variation due to permafrost degradation.

Rock glaciers are some of the most frequently occurring landforms containing ice in mountain environments. Here, we use field observations, analysis of aerial and satellite images, and dating methods to investigate the activity of the rock glacier of the Vallon de la Route in the French Alps. Our results suggest that the rock glacier is characterized by two major episodes of activity and that the rock glacier system promotes the maintenance of mountain erosion.
