the Onon River]] in the foothills of the Hentii Mountains, was close to both Genghis Khan's presumed birthplace and the site where he announced himself as the universal ruler of the Mongols. The site contained at least 20 unopened tombs for high-status individuals. An earlier Japanese expedition had visited the site in the 1990s, but was closed down over popular fears that the scientists planned to dig up the remains. On 6 October 2004, Genghis Khan's palace was discovered, leading to academic speculation that his burial site could alternatively be located nearby. In an account of a French Jesuit, Kravitz found a reference to an early battle where Genghis Khan, at the time still known as Temüjin, won a decisive victory. According to this source, the location was at the confluence of the Kherlen and "Bruchi" rivers, with Burkhan Khaldun over his right shoulder and after his victory, Temüjin said that this place would be forever his favourite. Kravitz, convinced that Temüjin's grave would be near that battlefield, attempted to find the "Bruchi" river, which turned out to be unknown to cartographers. He did, however, discover a toponym; "Baruun Bruch" ("West Bruch") in the area in question and as of 2006 was conducting excavations there, roughly east of the Burkhan Khaldun (, the wider area of Bayanbulag). In January 2015, Dr Albert Yu-Min Lin from the California Institute for Telecommunications and Information Technology at the University of California, San Diego set up a project asking anyone interested to tag potential sites of the burial through images taken from space. The project resulted in the publication of a paper in the journal Public Library of Science One that claimed to have identified 55 archaeological sites that could potentially be the final resting place of Genghis Khan. In 2015 and 2016, two expeditions led by French archeologist Pierre-Henri Giscard, a specialist in Mongolian archeology, and Raphaël Hautefort, a specialist in scientific imaging, around the Khentii mountains (North East of Mongolia) support the theory of a tumulus at the top of the Burkhan Khaldun mountain. Their non-invasive analysis, carried out with drones, showed that the -long tumulus is of human origin and probably built on the model of the Chinese imperial tombs present in Xi'an. In addition, the expedition noted that the mound was still the subject of religious rites and pilgrimages of the surrounding population. The expedition did not give rise to
