On September 2, 1806 heavy rains triggered a landslide from the Rossberg which destroyed Goldau and the adjacent villages of Busingen, Röthen and Lauerz. The landslide comprised 40,000,000 cubic metres (52,000,000 cu yd) of material, with a mass of 120,000,000 tonnes (118,000,000 long tons; 132,000,000 short tons).[2][3]
