The continuity implied by the existence of those rocks — the chain of physical events from the deposition of ancient sediments to the geological exposure of those sediments at the summit of a mountain above the Amazon basin — is one of the more extraordinary facts about the planet we live on.

And the current landform — the specific shape of Roraima as it stands today — is the product of erosion operating on those rocks throughout geological time, the current state of a process that was not finished and will not finish on any timescale relevant to human concerns.

Roraima as it looks today is not how it looked ten million years ago, and it is not how it will look ten million years from now.

The cliffs are retreating as erosion removes material from the face.
