In Selenge Aimag, between Sukhbaatar and the soum Altanbulag is a monument to Chinggis Khaan. It is near a spring that issues from the ground. It was in this area that Chinggis along with 60,000 troops camped whilst he searched for his favourite wiife. She had apparently been kidnapped by a rival.
The monument, along with most of the others through the country to Chinggis, is revered by the Mongolians. The spring nearby issues forth from the ground with clear, cool water. It is said that whistling over the spring causes the water to ripple on the surface. You can see Tseye trying this. As to whether the water rippled from the whistling or not, well, Tseye whistled, I watched but if you want to know, then travel to Selenge, visit the spring and whistle over the water and watch what happens.
