Windy Creek soil and landscape
Soil profile: Windy Creek soils are coarse-silty, mixed, active, subgelic Typic Histoturbels. Windy Creek soils have moderately deep mixed loess and alluvium over permafrost. (Soil Survey of Greater Nenana Area, Alaska; by Dennis Mulligan, Natural Resources Conservation Service)
Landscape: Windy Creek soils occur on alluvial fans and terraces. Vegetation is stunted black spruce (P. mariana) forest with an understory of mixed shrubs that include Labrador tea (L. groenlandicum), blueberry (Vaccinium uliginosum), lingonberry (vaccinium vitis-idea) and various willows (Salix spp.) with a thick ground cover of peat mosses (sphagnum spp.).
