A geography class at the Vaal becomes a rip-roaring rapid-filled razzmatazz for the learners from De La Salle College, in this video shot as part of an "educational" day on rivers. Thanks again to the enthusiasm of Ian and Veronica, geography teachers, the teenagers had some full-immersion education. All about water and rocks! This short trailer is only part of what was shot - it's too much to put on You Tube but we'll upload the fuller production on our shared DropBox site to be downloaded from there. Also on the DropBox is our short programme on how the Vaal came to be superimposed on the Vredefort Dome: one of the Earth's most remarkable river phenomena. - Graeme, The Riverman. 084 245 2490
