	Morphological Notes
	A11	Some wedge and polished peds at 25cm, also inwashed sand below 25cm. This 
	suggests possibility of a discontinuity. Manganese stains start at 380cm. From 360cm a 
	faint water stain (N6/) is associated with the slickensides. There is a sharp c
	A12	ontact between basal sand (above) and clay (below), at 552cm. Suspecten bone at 
	370cm, at 370cm 1 pebble (sandstone?) and a fragment of basalt. Topsoil texture is 
	"with sand".
	Observation Notes
	Parent Rock: alluvial sediment, clay,  parna on fourth fan
	Site Notes
	Site is more trampled than poached, near gate.
