I took this photo today on Cape Town's "Riviera" or Atlantic Seaboard. One sees Cape Town's upper cable station in the background. The building on the left is called the Douglas Clark Memorial Hall. Douglas Clark co-founded the Green and Sea Point Boy Scouts in 1909 with Norman Hill. I do not find any map (including Google) which offers the name of this river. Or rather, I only find "Table Mountain River", which seems unlikely.
