Soil Map Unit 6Hummocky microrelief ischaracteristic of the terrain on whichthese soils occur .The soils havedeveloped on fairly thick depositsof silt loam textured volcanic ashponding of meltwater accumulation .in small basin areas subject toThe hummocky soil surface isprobably a result of frost action .Classification :These soils pose a problem in classification .The pyrophosphateextractableiron and aluminum andthe organic carbon content of the Bhorizons are sufficient for Bhf horizon definition, thus the soils canbe classed as Ferro-Humic Podzols ;and since they have a deep Ah, asSombric Ferro-Humic Podzols .They are perhaps best classified as TurbicSombric Ferro-Humic Podzols due to their weakly cryoturbated surface .However, it should be noted that such a subgroup is not defined in theCanadian Soil Classification System .Associated Map Units :Map Units 1 and 8 are usually adjacent to Map Unit 6, on thewell drained slopes surrounding the basins .Vegetation :The hummocks generally support a continuous cover of Carexnigricans with very few other species present .Pedon Description :Described by : L .
