	Morphological Notes
	AC1	0-10 has conchoidal fracture suggesting a recent deposit without soil structure. Ditto for
	 10-20. I accept this as recent fill or surface wash over prior soil mainly on evidence of 
	inwashed sand from 20-30. Possibly just local redistributio

	This is the backslope of a levee related to a drainageway .75km N. Tendency to weak crust. Few large cracks to 40mm wide 
	show through cultivated surface; 600mm deep. Slicks at bottom of core. Boggy Creek is a prior stream with low terrace s
