	Morphological Notes
	A11p	Smith and Ward. Horizon designation according to new rules. Ap shearvane, 
	penetrometer and tensile strength not measureable. A1 contains quartz coarse 
	fragments. 131.04 ped faces tend towards slicks, but no proper slicks are developed. 
	A12	05 shearvanes and penetrometer do not penetrate. Carbonate nodules are uniform 
	throughout. 131.05 is stony light medium clay. Fresher rock below 130, 2.5Y5/0.

	Parent Rock: residual, basalt, sand Nandewar Volcanics
	Site Notes
	A large number of waterworn quartz gravels up to 100mm diameter and coated with iron occur on the surface. There are also 
	large basalt lumps to 200mm diameter. The surface is very good self mulching. Stones are sarsens (GMR) or ?aboriginal
