21extremely sloping land surfaces on the sides of the glaciated bedrockridges .Soil creep on these slopes seems to be primarily responsible forthe development of deep (10 to 50 cm) Ah horizons (Plate 2) and the loweriron and aluminum contents in the B horizons .While most of these soilsare classified as Brunisols, there is sufficient mobile iron and aluminumpresent in the B horizons of some of the soils to meet the requirementsfor Podzolic soils .Surface drainage on these steep slopes is rapid and there are fewboulders on the surface .Vegetation consists mainly of herbaceous plantsand grasses . Common species include Veratrum viride , Epilobiumangustifolium , Heracleum lanatum , Erythronium grandiflorum , and Elymus sp .The following is a brief description of an Orthic Sombric Brunisol profiletypical of map unit 2 soils .Horizon Depth (cm) Color Texture I C .F .

Thesteep slopes on which these soils occur and the resulting soil instabilityresult in severe limitations to use and a very high susceptibility to erosionif plant cover is removed .
