The retreat of Alpine glaciers is a clear indicator of climate change, with significant implications for hydrology, geomorphology, and local ecosystems. This study focuses on the glaciers of Val Ferret, located on the Italian side of the Mont Blanc massif, applying the GLATE (Glacier Thickness Estimation) model to estimate ice thickness distribution. The model is constrained using Ground Penetrating Radar (GPR) data, improving the accuracy of thickness estimations compared to traditional empirical approaches. The GLATE model was applied to several glaciers in Val Ferret, including Pré de Bar, Grapillon, Planpincieux, Whymper Serac, Col del Gigante, and Toula glaciers. Results indicate significant spatial variability in ice thickness, with greater depths in accumulation zones and severe thinning in ablation areas, confirming the accelerated retreat of these glaciers.
