-114-001 Map Unit (Sombric Humo-Ferric Podzols)This map unit is characterized by non-lithic soils which occur on colluviu mat elevations above the continuous forest line . Medium textures and coarse fragmen tcontents of about 20% are typical of this map unit, as are turfy Ah horizons up t o25 cm thick . Evidence of solifluction is often seen on this map unit .Table 40.

It is characterized by lithic soils which are found at elevation sabove the continuous forest line . Medium textures and coarse fragment contents o f20% or less are typical . The depth of fine earth materials over bedrock is characteristicallyless than 50 cm and a turfy Ah horizon is generally present .
