FALLING ROCK—Quebec, Mont St. Hilaire. Michel and Daniel (18) DeRoy finished climbing the Voie Normale on Mont St. Hilaire on October 22, 1972, and stopped for a cigarette and unroped. Michel told his brother to stay where he was and descended to find the way off. When he was returning, Daniel slid down with a large rock about 30 feet to the left of and higher than where he had left him, lost his helmet when the straps broke and was killed. Daniel had started to climb a ridge which was capped by the block. (Source: Michel DeRoy, translated and edited by E. Whalley.)
