Nice metaphor, but is it right? I don't think mountains ever get built by laying down layers of sediment. Sand castles, maybe, but mountains? Those need earth quakes, or at least plate tectonics.
In some sense, Jobs was an earth mover who could shake up the earth and make what previously was a sandplain into maybe not a mountain but at least a hill.
"The rocks making up the mountains were formed before the mountains were raised. [...]
The Rocky Mountains took shape during an intense period of plate tectonic activity."
Sediment (from the Latin sedere=to sit") doesn't move up a hill to turn it into a mountain. The wind may blow it up a bit to form dunes, but there is no way it forms anything resembling a mountain. I am not a geologist, though, so educate me.
