Overview

• The explorers became trapped by mid-sized rock blocks in the Diémort cavity beneath Dent de Crolles, approximately 1.5 hours from the entrance.
• The Orsec civil security plan was activated at 2:30 PM on June 8, mobilizing nearly 80 responders from SDIS Isère, CRS Alpes, gendarmerie and speleo rescue units.
• Rescue teams cleared debris and escorted two speleologists to safety late Sunday after navigating constricted, unstable passages.
• Medical personnel reached the injured caver Sunday night and a specialized crew extracted him at 7:00 AM on June 9 before airlifting him to Grenoble hospital in a very reassuring state, officials said.
• A companion at the cave entrance sounded the alarm when the group did not emerge, ensuring a swift, multiorganizational response.
