title: Investigation of a cold-based ice apron on a high-mountain permafrost rock wall using ice texture analysis and micro-<sup>14</sup>C dating: a case study of the Triangle du Tacul ice apron (Mont Blanc massif, France)
abstract: Abstract 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 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 apron. Texture (microstructure and lattice-preferred orientation, LPO) analyses were performed on one core. The two remaining cores were used for radiocar
