	Morphological Notes
	A11	Rare modern bone at 370cm, at 370cm 1 pebble (sandstone?) and a fragment of basalt. 
	Topsoil texture is "with sand".
	Observation Notes
	Parent Rock: alluvial sediment, clay, mixed texture, with lime parna on third fan
	Site Notes
	Slope 30 min. south. Some surface cracks visible here and there. Firm surface, breaking easily to coarse self-mulching. 
	Gravelly at base.
