Live: A treasure that has lain dormant for millions of years - Black Oil Mountain of Karamay

Black Oil Mountain is located in the northeast of Karamay, Xinjiang, more than two kilometers away from the city center. It is an important site for oil fields to outcrop. Due to the overflow of crude oil over the years, it has formed a group of asphalt mounds. The largest one is 13 meters high and 0.2 square kilometers in area. Crude oil is of excellent quality and does not condense easily.
