Further detail is hardly required: Qumbu has only two streets running
North/South and (as best I can recall -- though Google now shows a few more) only three running East/West.
Qumbu is on the national road N2, just North of the Tsitsa River:
a few miles to the east is the old Shawbury mission station, and
downstream from there are the Titsa Falls -- 375 feet. And a few
miles below that the Tsitsa and Tina unite and then join the Umzimvubu
which has its mouth at Port St Johns.
