  • Y03-11-12 - 230-255 cm - Soil 5 – Bmk – infilled squirrel burrows immediately below
  • Y03-11-13 - 255-300 cm+ - Loess
    Additional notes on modern soil & paleosols:
    Soil 1
  • consists of Bmk horizon material with 2 distinct colours: 7.5YR 4/3 d & 10YR 4/3 d
  • loess between Soils 1 & 3 is sandier
    Soil 2
  • 90% Ahk material, 2-10 cm thick
  • Ahk – 10YR 3/2 d
  • Bmk – 7.5YR 4/2 d
  • less abundant carbonate than in paleosols & loess below
    Soil 3 - most of exposure has Ahk (2-5 cm thick) over Bmk (4-10 cm thick), with carbonates as for Soil 5
    Soil 4 - mostly Ahk (10YR 3/2 d) material 2-8 cm thick, some Bmk (10YR 4/2 d) < 2 cm thick, with carbonates as for Soil 5
    Soil 5
  • complex intermixing of Ahk & Bmk material, charcoal most abundant in Ahk
  • individual colour bands 2-10 cm thick
  • overall dip of horizons (10° to W) is parallel to surface
  • similar size & density of secondary carbonates as in loess above & below; associated with root channels, < 5 mm diameter, covering ~ 5% of surface
