Investigation of a cold-based ice apron on a high-mountain permafrost rock wall using ice texture analysis and micro-14C dating: a case study of the Triangle du Tacul ice apron (Mont Blanc massif, France)
The current paper studies the dynamics and age of the Triangle du Tacul (TDT) ice apron, a massive ice volume lying on a steep high-mountain rock wall in the French side of the Mont-Blanc massif at an altitude Dryer Ball close to 3640 m a.s.l.Three 60 cm long ice cores were drilled to bedrock (i.e.the rock wall) in 2018 and 2019 at the TDT ice apro
