	Morphological Notes
	A11	The cause of the second colour is sand in layer 4 and clay in layer 3. There is inwashed
	 silica sand (in a crack) in layer 5. Though rock prevented more sample being collected,

	none was brought up from the bottom of the core. The topsoil is
	A12	 brown, and brown soil appears in cracks in layer 3 and below, suggesting a possible 
	basaltic surface wash. The quartz sands in cracks are below this and may be earlier 
	wash (sample to McTainsh). Residual on basalt talus, 50ft below summit 
	A13	of basalt hill. Silica sand source needs identification.
