Huanglong Scenic and Historic Interest Area
One of the greatest geologically interest is the extensive calcite deposition that has taken place. These are extensive slopes of active limestone deposition, covered entirely by a thin layer of flowing water. Huanglong has been noted since ancient times. A pair of small stone pagodas is found in the Yuya ponds at the head of Huanglong Valley. There are many legends associated with various natural features in the area.
