Yardang National Geopark is a park in Dunhuang with large scale yardang landforms, formed by wind erosion. It is a rare natural museum of naturally-formed sculptures, with ordered mounds in peculiar shapes. You can see the yardang landforms, watch the sunset, and learn about the legend of the 'Ghost City'.

The yardang-dune coexistence and the control of yardangs on dune formation reveal the joint action of wind erosion and deposition. Yardangs exhibit distinctive characteristics of streamlining and clustering, which apply unique and complicated impacts on the wind field and sand transport.

A yardang is a wind-eroded hill with a steep and broad front and a narrow end. Learn about the morphometry, subtypes and terrestrial and planetary examples of yardangs from the Encyclopedia of Planetary Landforms.

A yardang is a wind-eroded ridge or bank created by the erosive and constructive effect of wind on the Earth's surface. Yardangs form in arid environments where water is scarce and the prevailing winds are strong and unidirectional. They come in various shapes and sizes, from small to large, and can be observed on the Earth and Mars.

Yardang is a term for rock surfaces that have been shaped by wind erosion into ridges and furrows parallel to the dominant wind direction. Learn about the features, distribution, and formation of yardangs in different deserts of the world.

The meaning of YARDANG is a sharp-crested ridge carved by wind erosion from soft but coherent deposits (as clayey sand).

Yardang National Geopark is a scenic area in Gansu Province, China, famous for its wind erosion landscape of sculpted rocks and shapes. Learn how to tour the park, see the sunset, and enjoy the legend of its name.

The hyperarid Qaidam Basin features extensive fields of yardangs (covering an area of ~ 40,000km 2) sculpted in tectonically folded sedimentary rocks. We extracted the geometries of 16,749 yardangs, such as length-to-width ratio (L/W), spatial density, and spacing, from multi-source remote sensing data provided by Google Earth™.

(d) The largest yardang field on Earth, the Qaidam basin, China (38.262737°N, 93.044988°E). In a two-part series of papers, Pelletier et al. ( 2018 ) present a series of important advances that quantitatively explain how yardangs form and evolve.

A yardang is a streamlined protuberance carved from bedrock or any consolidated or semiconsolidated material by the dual action of wind abrasion by dust and sand and deflation. Yardangs become elongated features typically three or more times longer than wide, and when viewed from above, resemble the hull of a boat.
