This soil has formed in loess and has silty textures throughout.
Native vegetation consists of grand fir and ninebark.
Perched zones of saturation form above the fragipan during winter and persist into late spring, causing erosion hazards on steeper slope. Surface-applied fertilizers may also be transported laterally through these perched water tables, creating both economic and environmental concerns. Land use planning for these soils must take into account the special erosion and nutrient-mangement issues created by the presence of these saturated zones.
