-117-OP 1 Map Unit (Cumilic Regosols )This map unit is characterized by soils with little horizon development o nnon-calcareous fan alluvium . These soils are medium to coarse textured with coarsefragment contents of 20% or more . The coarse fragments are mainly Gog Grou pquartzites . The Regosolic nature of these soi Is suggests that they are subject t ooccasional stream channel shifting and/or overland flow during the spring runoff .Table 42 .
