50 years ago, on August 30 1965, a glacial slide of the Allalin-glacier near Mattmark in the Valais buried and killed 88 mostly Italian construction workers under 500 000 m3 of ice. While the migration treaty of 1964 had helped to ease relations between Italy and Switzerland, the catastrophe of Mattmark led to their renewed deterioration. Cf. dodis.ch/G9174.
