Description
The Mer de Glace glacier on Mont Blanc’s north flank has been retreating rapidly under climate change, but its upper accumulation zone still presents one of the world’s most spectacular glacier crevasse systems. This aerial photograph, made from a helicopter at 50m altitude above the glacier surface with full DGAC authorisation, looks directly into an open crevasse approximately 20m wide and at least 30m deep, the ice walls ranging from surface white through pale aquamarine to the deep indigo-black of maximum ice depth. The photograph has been widely used in climate change communication, glaciology research, and alpine photography exhibitions, and carries a strong visual argument about glacier scale and structure that transcends its documentary subject.
