Location Coordinates: 61° 2’ 3.6” N, 138° 22’ 48.8” W, 806.7 m asl (± 8.7 m)
Site Description: roadcut through SW-facing hill exposes loess over glaciofluvial gravel, with 4 paleosols in colluviated loess
Sample Depths & Descriptions:
- Y03-11-01 - 0-18 cm - ACk (fresh loess)

- Y03-11-08 - 170-198 cm - Loess with secondary carbonate in root channel
- Y03-11-09 - 198-202 cm - Soil 4 – Ahk – laterally continuous for ~ 1.5 m
- Y03-11-10 - 202-230 cm - Loess with secondary carbonates in roots
- Y03-11-11 - 230-255 cm - Soil 5 – Ahk – includes abundant charcoal bands
- Y03-11-12 - 230-255 cm - Soil 5 – Bmk – infilled squirrel burrows immediately below

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
