Totalanika soil and landscape
Profile of Totatlanika fine-silty, mixed, active, subgelic Typic Histoturbels. Totatlanika soils have moderately deep mixed alluvium over permafrost. Segregated ice seen in this photo starting around 70 cm are common in these soils. (Soil Survey of Greater Nenana Area, Alaska; by Dennis Mulligan, Natural Resources Conservation Service)
Landscape: Totatlanika soils occur on flood plains. 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 vaious willows (Salix spp.) with a thick ground cover of peat mosses (sphagnum spp.) and tussock forming sedges (Eriophorum spp.).
