THE NOVEMBER ECO-QUIZ WAS:
1 Lake, 2 World Records, 1 National Record. Name the country, the lake, and the records ! 
The answer was: Lake Tianchi ("Heaven Lake"), on top of Mt. Changbaishann ("Ever-White Mountain") in northeast China's Jilin Province at the border with North Korea. The lake and the mountain are listed by the UN as an area of special interest, as home of many rare plants and animals. The two "world records", recognised by certificates from the Guinness Book of Records in 2000, are (1) that it is the highest volcanic lake in the world at 2,189.1 metres and (2) it has the largest waterfall (68 metres) originating from a crater lake. (Strangely enough the volcanic lake in Ecuador, Quilotoa, next to ECOCLUB Member Lodge Black-Sheep-Inn is higher, maybe we should tell Guiness). The one National Record is that it is the deepest mountain lake in China with an average depth of 204 metres.
Somewhat predictably there were no winners.

THE DECEMBER ECO-QUIZ IS (an easier one...:)
