	Morphological Notes
	A11p	This site could receive recent deposits of alluvium. Well structured B horizon.
	Observation Notes
	Parent Rock: alluvial sediment, clay,  parna on fourth fan
	Site Notes
	Prepared seed bed. Surface cracks hidden by seed bed. Near sunset a very low microrelief is seen, a ripple effect in surface, 
	wavelength 4 metres depth approx 10 cm, running E/W while seed bed runs NE/SW.
