Bono (Riau)

Bono is a curious natural phenomenon, which the Rokan River (in the Kampar regency) displays daily along its downstream reaches. Every day at the time high tide sets in, a swelling appears in the water at the river mouth.
Accompanied by a rumbling sound, the swelling grows in mass until it is about as high as a small tree, spinning as it moves upwards along the river and growing smaller in the process until it finally disappears.
