Detailed Soil Survey of the Mount Revelstoke Summit Area.

49The soils of map units 1, 8 and 9 have the least severelimitations to use, especially where they occur on Cto E topographyclasses (2 to 15 percent slopes) . These soils have sandy loam textures,are well drained,fairly stable, and generally have high infiltrationand permeability rates .Permeability, however, may be restricted in theortstein layers in some of the map unit 9 soils .Surface stoniness andbedrock outcrops may result in moderate limitations in some of the soils .The areal extent of these soils on suitable slopes is small, however .Limitations to use of an area may also arise from vegetationparameters .Aspects of vegetation fragility have been studied by Landalsand Scotter (in preparation)and a consolidated rating of fragility ofecological units, employing vegetation and soils limitations was made .This environmental fragility rating is explained in the included reportby Knapik and Landals (page 60) and the rating of the area is shown onthe Fragility Rating Map .
