rereading o'brien & lyman's "seriation, stratigraphy & index fossils" i realised they don't mention or even reference harris or the harris matrix (altho they do cite adrian praetzelis' article in harris' "practices" book)
how wide-spread is use of the harris matrix &/or his theories of stratigraphic theory in the US?
also: does anyone colour their plan/profile drawings using pencil crayons? & if so, do they try for naturalistic colours, or use some form of abstract code or hatching to represent soil texture/composition?
