	Morphological Notes
	A11p	This profile is quite wet to 100cm, so may be masking structure. From 120cm, the coarse
	 sand increases to 167 where there is a strong sedimentary break but not soil break,

	thus no buried soil (WTW). But this may equally well be a soil break
	A12	 (DMcG). MVpH.
	Observation Notes
	Parent Rock: alluvial sediment, mixed texture, non-calcareous, mixed texture, with lime parna on third fan
	Site Notes
	Fallow after wheat. A grey clay surface, well mulched. Very flat. No surface stones visible.
