295-a20 cm-5 -bPlate 5 .The hummocky soils of map unit 6 are found in small enclosedbasins (5-a) where snowmelt water ponds in July . These soilsare classified as Sombric Ferro-Humic Podzol due to the presenceof Ah and Bhf horizons . Soil parent materials are predominantlyvolcanic ash .
, The soils have developed in volcanic ash deposits with predominantlysilt-sized particles which are highly susceptible to frostaction .The densely rooted turf formed by the Carex overlies thick Ahhorizons and B horizons that have sufficient content of organic carbonand iron and aluminum to qualify as Bhf horizons .These are the only soils in the area with hummocky microtopography.The following is a brief description of a Sombric Humo-FerricPodzol typical of map unit 6soils,Horizon Depth .

Surface drainage is rapid .These soils occur under predominantly herbaceous vegetation,often in open forest stands .Common herbaceous species include Seneciotriangularis , Ligusticum canb i, and Erigeron peregrinus .
