SOIL SURVEY

-127-Landform and Parent Material sThe Schaffer soilscape group generally occurs on morainal veneers andblankets overlying bedrock . The materials are generally calcareous, mediumtextured till but a few coarse textured non-calcareous tills are included with thi ssoilscape group . The coarse textured tills occur mainly in Eagles Eyrie and th eupper Cataract Brook - McArthur area .EnvironmentThe Schaffer soilscape group occurs in the Krummholz portion of the subalpin evegetative zone and in the alpine vegetative zone . Tree cover is less than 10% an delevations are above about 2150 m a .s .l .SK 1 Map Unit (Sombric Humo-Ferric Podzols )This map unit is characterized by those soils which have developed on glacia ltill at elevations above the continuous forest line . The soils of this map unit ar egenerally medium textured, (with the exception of those in the Eagles Eyrie and th eupper Cataract Brook - Lake McArthur areas which may be coarse textured), contai nless than 50% coarse fragments, and are usually well to moderately well drained . Aturfy Ah horizon is characteristic of this map unit . Small earth hummocks may for min the imperfectly to poorly drained depressions which occur as inclusions withi nthis map unit .
