Sprawling on the edge of Mount Bogda and 100 km east of Urumqi, Tianchi Lake and the surrounding Tianshan Mountains must define the word "beauty" in the Uygur language since there is no more beautiful place within the autonomous region. Tianchi runs 4.9 square km in area and 90 meters deep; a natural lake surrounded by snow-capped peaks and sky-scraping dragon spruce fed by thawing snow runoffs.
