crystal palace - China Travel

introduce

Crystal Palace is an ice cave. This karst cave is that the magma erupted by the volcano is affected by the cold air during the flow process, and the surface is solidified into a hard shell, while the rock flow in the lower part continues to flow, and a hollow is formed where the subsequent magma is insufficiently replenished. Influenced by the low temperature of the layer, after the entire magma condenses, an eternal lava ice cave will be produced. The Crystal Palace is 150 meters long and 23 meters deep. The hall in the front of the cave is 400 square meters. There are two branch side caves with a height of 6 meters. It is a strange-shaped lava flow mark, and the roof of the cave is a lava stalactite that hangs down and drips. Jade-like frost flowers are all over the cave roof, which are crystal clear, adding a bit of softness and delicate beauty to the rough underground cave. The ice at the bottom of the cave does not melt all year round. Entering the fairyland, in the Northeast, it is not surprising to see ice and snow in winter, but it is indeed a miracle to experience "winter in summer". The four wonders and four monsters of Wudalianchi "Snow and Ice in Three Volts" refer to this place.
