SOIL SURVEY

- 92-Landform and Parent Material sThe Narao soilscape group occurs on flat bog and horizontal fen landforms .The materials consist of mesic and fibric organic layers overlying calcareous alluvium .Environmen tThe Narao soilscape group occurs on very poorly drained sites within th emontane vegetative zone and the lower portion of the subalpine vegetative zone .NA 1 Map Unit (Terric Mesisols )This map unit is characterized by organic soils with neutral reaction an ddominantly mesic organic layers . Calcareous mineral materials are usually encountere dwithin 130 cm of the surface . This map unit is generally located at about 1200 m a .s .l .Table 28 .
