Soil Description, Plot SW-24

	Microsite: Palsa in colluvial basin. Substrate: Organic-rich basin deposit. Vegetation: Moist Betula nana exilis, Rubus chamaemorus, Ledum palustre decumbens, Dicranum elongatum, Sphagnum sp., Cladonia spp., dwarf-shrub, fruticose-lichen tundra Classification: Hemic Pergelic Sphagnofibrist; classification based on assumption that there is no mineral horizon within 10 cm below permafrost table Notes: Permafrost at 39 cm. Water table at 38. Horizons: Oi 0-15 cm. Bright reddish brown to yellow orange (5YR 5/8 to 10YR 8/4) very porous loose fibric peat composed of Sphagnum bases; clear smooth boundary. Oe 15-32 cm. Brownish black (5YR 2/2) compressed hemic Sphagnum peat; est. less than 2% loamy mineral material; moderate medium platy structure; many fine and very fine roots; abrupt smooth boundary. Oa 32-39+ cm. Very dark brown (7.5 YR 2/3) sapric Sphagnum peat; est. 10% silt loam mineral material by volume; moderate medium granular structure; slightly sticky, slightly plastic (wet); many fine and very fine roots binding the soil, common fine roots below water table at 38 cm.
