	Morphological Notes
	A11	Originally bu015. Top 15cm is recent flood deposit. 230-240cm sampled by mistake for 
	250-260cm (also sampled). Pian. The hard concretions at 70-80cm are somewhat 
	irregular and lumpy. As the soil is deep, dark, well structured and carbonate-
	A12	rich, I prefer prairie soil to grey clay. Parent sediment below 130cm is weakly weathered.
	Observation Notes
	Parent Rock: alluvial sediment, clay, mixed texture, with lime first terraced fan, Namoi
	Site Notes
	Shallow surface deposit over Pian sediment. Low terrace. Slight levee rise. Poplar box.
