sandstone wave. Click the pic for full resolution.
What you are looking at is an entirely natural landscape – it is a sandstone rock formation, formed when dinosaurs roamed the Earth, in the Jurassic. Dinosaurs went extinct and the U-shaped formation got eroded, and after their formation, the drainage basin, which fed rainwater to these troughs, shrank to the point that that the runoff became insufficient to contribute to the cutting of these troughs. As a result, they are eroded now only by the wind, as indicated by the inclined erosional steps. The direction of the wind also gives the general direction and the funnel-like appearance.
Andrei is no scientist, but from an early age, he has been fascinated by science; that's why he went to college, and signed up for Geophysics. Feeling that there's a huge gap between science and average people, he rallied TP, started ZME Science, and gave it a green twist too.
