Abstract
Abstract. The soils of a deposition hill of an ancient mountain slide, from a serpentinitic region called Totalp, were investigated and mapped. The investigation area lies east of Wolfgang (1631 m above sea level) near Davos, Switzerland. In spite of the subalpine climate, which generates iron-humus-podsols on acid Silicates, acid brown earth was found on serpentinitic parent material. Slightly visible eluvial horizons that were found occasionally below the raw humus consisted primarily of quartzsilt, which was thought to be of aeolian origin. Mapping elucidated the boundary between two mountain slide depositions. The first slide to occur (deposition area: Drussetschawald/Lusiwald) consisted mainly of acid Silicates mixed with some serpentinite, whereas the slide that followed (Delenwald/Budlerboden) consisted of pure serpentinite. This second slide only covered the first marginally.
