SOIL SURVEY

-125-SI2 Map Unit (Lithic Humo - Ferric Podzols )This map unit is characterized by lithic soils which occur in the uppersubalpine ecotone . Medium textures and coarse fragment contents of about 20%are most typical of this map unit . A turfy Ah horizon is often, but not alway spresent . The depth to bedrock is generally less than 50 cm on this map unit .Table 46 . Brief description of the pedon chosen to characterize the SI2 map unit .HorizonDe (cm) p)Moist ColorEst .
