Mooi
The Mooi River crosses the highveld before joining the Vaal. Springs in the dolomitic country along its course feed its waters and those of the Wonderfonteinspruit, one of its tributaries. By the early nineteenth century the land north of the Vaal was home to Sotho-Tswana communities. To the west lay the country of the Barolong, while Kwena and Hurutshe chiefdoms held lands farther north around the Magaliesberg and the upper rivers beyond it.
