added by archaeologs This great waterfall on the Zambezi River, on the border between Zambia and Zimbabwe, has cut its way back along a zig-zag series of successive fall-lines. The area is of particular archaeological interest in view of the artefact-bearing gravels which were originally laid down by the river and which have now been left on the lips of the gorges through which the Zambezi presently flows below the Falls. Further archaeological sites are preserved in the sand deposits of the valley flanks both upstream and downstream of the Falls. Pioneer research in this area contributed much to the elucidation of the Stone Age archaeological sequence of southcentral Africa. Association of archaeological material with the various stages by which the Falls have retreated to their present position offers the possibility of establishing a chron-logy for the latter process.
