• Mesa
  • Huayin City

A mesa is an isolated, flat-topped elevation, ridge or hill, which is bounded from all sides by steep escarpments and stands distinctly above a surrounding plain. Mesas characteristically consist of flat-lying soft sedimentary rocks capped by a more resistant layer or layers of harder rock, e.g. shales overlain by sandstones. The resistant layer acts as a caprock that forms the flat summit of a mesa. The caprock can consist of either sedimentary rocks such as sandstone and limestone; dissected lava flows; or a deeply eroded duricrust. Unlike plateau, whose usage does not imply horizontal layers of bedrock, e.g. Tibetan Plateau, the term mesa applies exclusively to the landforms built of flat-lying strata. Instead, flat-topped plateaus are specifically known as tablelands.

Huayin, which belongs to Weinan City, Shaanxi Province, is famous for its Xiyue Huashan, located in the east of Guanzhong Plain, the combination zone of Qin, Jin and Henan provinces, Tongguan in the east, Huazhou District in the west, Qinling Mountains in the south and Weishui River in the north, between latitude 34 °19 °22 "- 34 °40 °00" and longitude 109 °54 "- 110 °12 °13" east, with a total area of 817 square kilometers. Huayin set up cities in the Spring and Autumn period and bought counties in the warring States period. It has a history of more than 2300 years. Since ancient times, it has been known as "the main roads of the three Qin dynasties and the thoroughfares of eight provinces". It is a necessary place for the Central Plains to go to the northwest. Approved by the State Council in December 1990, it is one of the four county-level cities in Shaanxi. In 1993, it was named as a famous historical and cultural city by the Shaanxi provincial government. Huayin City is the birthplace of Yang's family in the world.
