-60-Soil development on the fine earth materials, where present, is regosolic or brunisolic .The extreme stoniness causes very severe limitations for recreational an dengineering uses .BG2 Map Unit (Cumulic Regosols plus Cobbleland )This map unit is characterized by those soils, with little horizon developmen tand greater than 50% coarse fragments, which occur on colluvium . Commonly thi smaterial is recognized below cliffs or rock outcroppings which provide the supply o fcolluvial material . The instability of the soils within this map unit is indicated b ythe open tree cover and the high number of stunted and curved trees which are present .Snow avalanching is sometimes associated with parts of this map unit and is designatedas BG 2 +A where the avalanching occurs on less than about 25% of the map unit an dis restricted to well defined chutes, or as BG 2 A where avalanching occurs on greate rthan 25% of the map unit . These soils do not usually have an Ah horizon .Table 12 .
