Heaven Lake -- Tiānchí

Heaven Lake (天池 (Tiānchí) in Chinese) is a crater lake on the border between China and North Korea. It lies within a caldera atop the volcanic Baekdu Mountain, a part of the Baekdudaegan mountain range and the Changbai mountain range. It is located partly in Ryanggang Province, North Korea, and partly in Jilin Province, northeastern China.

The lake has a surface elevation of 2,189.1 m (7,182 ft). The lake covers an area of 9.82 km² (3.79 sq mi) with a south-north length of 4.85 km (3.01 mi) and east-west length of 3.35 kilometres (2.08 mi). The average depth of the lake is 213 m (699 ft) and maximum depth of 384 m (1,260 ft). From mid-October to mid-June, it is typically covered with ice. 

Many believe that the lake is home to the Lake Monster. It is unknown if the monster and legendary Kun are related. In 2007, Zhuo Yongsheng, a Chinese TV reporter said he had shot a 20-minute video of six unidentified creatures in the volcanic lake on 6 September. He later sent still photos to Xinhua's Jilin provincial bureau. According to a news report one of these showed the six "Nessies" swimming in parallel in three pairs. Another one of them featured the animals closer together, leaving circular ripples on the lake surface.

Zhuo said he had seen the six seal-like, finned creatures swimming and frolicking in the lake for an hour and a half, before they disappeared around 7:00 a.m. "They could swim as fast as yachts and at times they would all disappear in the water. It was impressive to see them all acting at exactly the same pace, as if someone was giving orders," he said. "Their fins—or maybe wings—were longer than their bodies."
