Where slopes are no tlimiting, moderate limitations are present due to the silty surficial texture and th epotential frost heaving . The severe climate associated with this map unit also result sin a high susceptibility to environmental damage .TA - Takakkaw Soilscape GroupPhysiographic Setting (Figures 34, 39 , pages 67, 72)Members of this soilscape group are found throughout the lower subalpine an dmontane regions of the Park, generally at the confluence of two or more major valley swhere kame terraces and other stratified drift materials are located .
