Under pristine conditions and with its wealth of stone tools, petroglyphs, bronze and iron tools, tombs, ruins of cities and towns, and other valuable historical and cultural monuments the Gobi Desert attests to being the birthplace of mankind, as does its significant paleontological discoveries, such as the petrified fossils of dinosaurs that existed over 80 million years ago, sea creatures and plants, petrified wood, footprints of marsh heron, zebu, and ostriches inhabiting the area 30 million years ago.

The region has been explored over a lengthy period by the Italian trader Marco Polo, the Russian geographer N. M. Prjevalsky, the Russian scientist and geographer V. I. Obruchev, Russian tourist P.

Sainshand. Population 20,000. Elevation 938m. One of Mongolia's most dusty and dry aimag capitals, Sainshand (Good Pond) is important primarily because of it's location. The city was founded in 1931 and was called Tushet Khan aimag during Manchu rule. It is on the main rail line to China, and not far from the Chinese border.

As it is a station on the main train-line of the Trans-Mongolian line of the Trans-Siberian Railway from Beijing via the Zamiin-Uud/Erlian border crossing to Ulaanbaatar, there is little public transport otherwise. A paved road was completed in 2013 connecting Sainshand and Zamiin-Uud to Ulaanbaatar via Choir. No word yet if there will be any buses between the cities.
