	Morphological Notes
	A11p	Very large cracks on surface. Sunflower recently harvested. Surface condition dry 
	(good fine self-mulching top), subsoil reddish, slight reddish tint to field topsoil. ?old 
	alluvium. Topsoil is quite dark. From 280cm, a break to sandy clay 
	A12x	with large infilled cracks. This appears to be discontinuous with upper soil material. No 
	bedding of sand grains evident. Compacted (?by cultivation) from 9-18cm.
	Observation Notes
	Parent Rock: alluvial sediment, clay, mixed texture, with lime parna on fourth fan
