- 88-Figure 51 . Site of the pedon chosen to characterize the KI2 map unit .This site is quite wet for short periods in the spring but ofte ndry in the summer and fall . Open canopiedforest with junipers and shrubby cinquefoi lare common .Figure 52 .Gleyed Cumulic Regosol soil chosen tocharacterize the K12 map unit . Lime occur sto the surface . The finer textures near th esurface result from deposition of calcareou ssilty material from flood waters .
-89-Wetness, texture, and potential flooding hazard result in moderate and sever elimitations for most recreational uses as well as for buildings and roads .MO - Mollison Soilscape GroupPhysiographic SettingMembers of this soilscape group occur on fluvial fans which derive a majorportion of their sediments from igneous (nepheline syenite) outcrops . In Yoho, igneousoutcrops are restricted to the Ice River area (except for occasional small dykes) .Because the major source of sediments for a given fan can be different on adjacen tfans soils of the Mollison soilscape group alternate with those of the Watchtowe rsoilscape group as the successive creeks enter the Ice River Valley .Landform and Parent Material sThe Mollison soilscape group occurs on fluvial fans and aprons . The material sare non-calcareous, stratified, gravelly and cobbly, coarse textured fan alluviumderived mainly from igneous rocks .EnvironmentThe Mollison soilscape group occurs on well drained valley bottom site swithin the montane vegetative zone in the Ice River valley .MO1 Map Unit (Orthic Humo-Ferric Podzols )This map unit is characterized by soils which developed on the alluvia l(fluvial) fans in the Ice River Valley . These coarse textured soils generally contai nmore than 20% of dominantly igneous coarse fragments, are moderately stony and ar eusually well drained .
