Rock Glacier Program

In this article, I detail the use of ground-penetrating radar (GPR) to highlight the structure of Sachette Rock Glacier, Northern French Alps. I also present the results of measurements of annual surface displacements at the surface of the rock glacier. As a main conclusion, the rock glacier appears as deriving from a glacier having embedded… Read more

I present here the study case of Hurcones Inferior Rock Glacier and Debris-covered Glacier, located in the southern face of the Aconcagua, Argentinean Andes. Hurcones Inferior Rock Glacier takes place between 4400 m and 3810 m a.s.l. and overlaps/leans into Hurcones Inferior Debris-covered Glacier (Figure 1 and Figure 2). The rock glacier is considered as… Read more

In a previous article, I reported the discovery of the potentially largest rock glacier on Earth, in Xinjiang Mountains, China. I call this rock glacier Xinjiang I Rock Glacier. The valley in which Xinjiang I Rock Glacier takes place is Xinjiang I Valley. Basing on GIS geomorphic mapping (Figure 1), I provide the further data… Read more

I have identified very large rock glaciers in the Xinjiang Mountains, China, ∼400 km east from Hotan city. I digitized the contours of the most prominent one, which takes place between 5480 m and 4680 m a.s.l. in a system of narrow north-facing hanging valleys with very small debris-free glaciers in their upper part. The… Read more

Introduction See the file: INTRODUCTION   Questions and guidelines (1) Will Aconcagua Debris-Covered Glacier evolve into a ‘true’ well-developed rock glacier and what will be the process time laps? (2) If we assume that the ice fraction of the system in its initial stage is close to 100%, how to model the evolution of both… Read more

In a global warming and glaciers’ recession context, it is important to study the possible preservation and regeneration of former glaciers’ ice in mountain environments, especially in semiarid or arid watersheds, in which the contribution of debris-covered glaciers and glaciers to river flows may be significant. One of the main topic related to glacier disappearance in… Read more
