Soil Map Unit 8These soils have medium textured, black Ah horizons overlyingdark reddish brown podzolic B horizons that are much sandier intexture .These soils are found mainly in the central part of the studyarea within the upper fringes of forest cover .Classification :These soils are classified asSombric Humo-Ferric Podzols dueto the presence of an Ah greater than 7 .5cm and a Bf more than 5 cmthick .There are no Ae horizons in these soils and only occasionallyan Ahe .Associated Map Units :Map Unit 8 soils are often associated with bedrock outcrops(R) and with lithic soil phases (Map Unit 10) . Map Unit 9 soils oftenborder and intergrade to the Map Unit 8 soils, with the Map Unit 9soils generally found under a heavier tree and shrubcover . Map Unit 8soils also grade to Map Unit 1soils which have lesspronounced podzolicmorphology and browner colored B horizons .Vegetation :Plant cover is often made up of Cassiope mertensiana ,Luetkeapectinata communities scattered clumps and individuals of Abies lasiocarpa .Pedon Description A : (This soil was described and sampled in two locations .)Described by : L .
