	Morphological Notes
	A11	The second colour in layer 1 is fine, pale coloured sand, spread through the clay. There 
	is some evidence that the cause is infilled cracks, but this has been masked by cultiva 
	tion. Structure from 5-45cm appears degraded, being almost mass
	A12	ive from 25-40cm. Beneath this there are slickensides with polished faces (from 50cm).
	Observation Notes
	Parent Rock: alluvial sediment, clay,  second terraced fan
	Site Notes
	Wheat stubble. Fine self mulching top is covering any cracks that may be there. This is a mostly flat site. Few quartzite pebbles 
	on surface (4cm diameter). The site lies at the foot of a small basaltic rise, and lies between this hill and
