	Morphological Notes
	A11	The top 10cm contains thin laminae of sand as well as inwashed sand. At 33cm a small 
	snail shell was found. The subsoil (120-130cm) colour resembles the colour of the 
	MVpH subsoils. Many small manganese flecks occur at 350-358cm, as well as
	A12	 coarse carbonate nodules at 320-330cm. This profile seems to have relatively thin flood 
	deposits (note sand laminae) over a prior soil like MVpH or alternatively, the oldest 
	alluvium.
	Observation Notes
	Parent Rock: alluvial sediment, clay,  floodplain
	Site Notes
	Small shells on surface due to ponding of Galathera Creek. Some cracks 840mm deep, but average 500mm. The cracks at this 
	site are very big possibly due to extremes in water content. NB. By definition there are 50 cracks per metre as there a
