China's Keping thrust belt produces awesome exposures of multi-colored sedimentary rocks where they are upturned and eroded above thrust faults. I made a simple sandbox model that illustrates the underlying structures that produce the belts of colored rock exposed in the real-life mountains. The model shown in the video was "eroded" (carved) in detail after it was gelled and partially dried.

Copy and paste either set of coordinates into Google Earth or Google Maps:
