Deutsch: Mit drei gleich langen Stöcken kann man einen Winkel von 30° bilden. Dies ist etwa bei der Beurteilung der Lawinengefahr nützlich; Lawinen entstehen fast nur bei mehr als 30° Hangneigung.
English: Using three equally long poles, one can form an angle of 30 degrees. This is useful e.g. to determine the avalanche risks. Nearly all avalanches develop on slopes with more than 30 degrees.
