	Morphological Notes
	A11	30-40 colour 2 an organic stain. Concretions in 30-40 include 5YR5/8. Some fine 
	manganese occurs in 173.04 according to GMR, but is not in significant visible amounts. 
	Mn stains become obvious at 90cm. Few mn/fe segregations also evident in
	A12	 upper part of B. Carbonate continues to about 200cm but not into reddish zone. The 
	lower part of the B2 is differentiated by its reddish colour. Depth 173.07 should have 
	been 350-360. Note conflict of calling site 173.03 an A2n without a h
	A2	orizon break from A12.
	Observation Notes
	Parent Rock: colluvial sediment, sandstone,  Pilliga Sandstone, weathered
	Site Notes
	Topography r1 to r2. Handshear: soft patches give 1.8. Handpen: soft parts give 1.6. The soft patches are small, adjoin grass 
	clumps, and are sandy. Soil grades to red so we take an extra metre.
