Roraima feeds all three.

The water that flows off Roraima does more than supply rivers.

The waterfalls that pour from the rim of the plateau are among the most visually spectacular features of the mountain.

Some fall freely in uninterrupted plunges of hundreds of meters.

Others cascade down the stepped face of the cliff in a series of drops, the water atomized into mist before it reaches the base, feeding the cloud that so often wraps the lower cliffs.

The quantity of water falling as rain on the summit — potentially four meters or more per year — is processed by the summit ecosystem and the cliff faces in complex ways that geologists and hydrologists are still working to understand.
