Unit	Description	HCl*	Field interpretation
1	Dark brown humic loam containing platy fragments of shale. Granular structure.	-	Current A horizon of a soil developed under an alpine meadow.
2	Platy subangular fragments (mean diameter 5-10 cm, max. 30 cm) of slightly weathered shale (ca. 70%) in a greyish brown loamy matrix (ca. 30%). Clast-supported with imbricated elements.	++	Coarse alluvial fan deposit.
3	Three sub-units each composed of slightly weathered granules and pebbles (shale and limestone) at the base and yellowish to grayish brown silty loam at the top. 	++	Alluvial fining-up sedimentary sequences
 possibly deposited in a lake. 
4, 5	Orange strongly weathered (almost decarbonated) pebbles (shale and limestone) at the base, light yellowish to grayish brown silty loam at the top.	-/+	Alluvial fining-up sedimentary sequences possibly deposited in a lake (affected by pre- or post-depositional weathering).
6	Light yellowish brown clayey silt with black and red mottles (Fe-Mn hydromorphism) especially at the base. Massive structure.	-	Aeolian sediments (in situ deposited or reworked by fluvial transport).
7, 9, 10, 17	Yellowish to grayish brown clayey silt. Massive structure, less consistent than unit 6. Laterally, presence of isolated pebbles and cobbles in units 7, 9 and 10. 	-	Aeolian sediments possibly deposited or reworked in a lake, with possible dropstones (10-15 cm).
8	Yellowish brown sandy loam containing orange weathered calcareous granules.	-/+	Alluvial input (affected by pre- or post-depositional weathering).
11, 12, 13	Greyish brown silty clay with strongly weathered (decarbonated) granules and pebbles at the base. Massive structure, very low consistency.	-/+	
15, 19	Similar to above but with little weathering of the pebbles.	++	Alluvial input.
14, 16, 18	Grey calcareous pebbles and granules (ca 60%) in a yellowish brown loamy matrix (40%). Clast-supported sediment with weathered imbricated elements.	++
