	has abundant, very fine white clay cementing the sand grains. Overall, this is a most 
	red/brown profile. Apparently well aerated. Co-author McGarry.
	Observation Notes
	Parent Rock: alluvial sediment, from sandstone, with lime,  Tertiary beds
	Site Notes
	Site located approximately 100 m from grid point. Field situated 100 m away has hard setting soil (by Northcote classification) 
	although natural soil is loose, not hard setting.
