-52-BC - Beaverfoot Soilscape GroupPhysiographic SettingFigure 18 . Sketch showing the landscape relationships between Beaverfoot andassociated soilscape groups .Landform and Parent Material sThe Beaverfoot Soilscape group occurs on nearly level to depressional fluvia lplains . The materials are calcareous, stratified, medium and coarse textured recentalluvium .EnvironmentThe Beaverfoot soilscape group occurs on poorly drained valley bottom site sgenerally within the montane vegetative zone, but occasionally extending into th elower part of the subalpine zone at elevations up to about 1600 m a .s .l .

Soils of this map unit have a peaty surface laye r15 to 60 cm thick, consisting of the remains of mosses and sedges . All soils of thi smap unit are medium to fine textured with less than 5% coarse fragments and havevery poor internal drainage . Mottles are present throughout the pedon .Table 8 .
