I
I remember I saved a clump of clay from the Dundas,, Ontario gorge near the escarpment and put it in a plastic bag for no good reason other than I liked the reddish brown colour. Artist Herman de Vries has made it his lifeswork travelling the globe in search of such colourfull specmens of such mud, soil and earth http://www.hermandevries.org/http://www.hermandevries.org/
Does it not encourage one to go play in the mud!!!
