	Morphological Notes
	A11p	A1p1 is compacted surface following cultivation when wet; A1p2 is prior cultivation. 
	One subrounded basalt stone (1-2cm) at 165cm depth. A horizontal biscuitty fracture 
	below 180cm, but much cast granular at this level too. A few soft calca
	A12p	reous segregations occur in faunal passages between 300 and 320cm. Rounded basalt 
	stones below 370cm stop hole at 395. Q, an alluvial terrace below pediment.
	Observation Notes
	Parent Rock: alluvial sediment, from sandstone and basalt, with lime,  second terraced fan
	Site Notes
	Site 345 is ca 300m from 344. Surface is hard-setting, but more clayey than 344. Brown clay surface. 10m S of fence.
