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.
