In March 2006, some members of Tokyo Speleo Club joined the exploration that organized by France team in China Guizhou (Guizhou-Kaolin2006). Taking the opportunity, we resume Fenglin Project as China Fenglin Project. It has been discontinuing the activity since 1988-1991.
On the research in the end of 2006 to the new year of 2007, we explored 16 caves including in Chuan Dong cave system (4316m) and Duancengyan Dong – Da Dong cave system (3366m) and we surveyed a total of 9491m.
However we can’t finish at the year. So this time we continued the survey. As a result Fengbei Dong reached 5km and connected underground stream for resurgence to plateau. Confirmation of this connection was an aim of this area’s survey.
On this time we sometime came back late into the night because of need to over 3 hours to reached survey point in Fengbei Dong. For example, final day same member came back daybreak on the morning. We may have to preparation of camp in the cave on hereafter activities.
These survey bring on 11days from the end of year to the New Year because of Japanese can take long holidays easily. We spend 4 days go survey area and back, and 1 day was a reserve day. We could use only 5 or 6 days for survey but could survey 7630m. On past 2 times expedition, we had totally only 10 days but could survey 16km. However it is not finish the survey of all caves. But we may be able to grasp on outline of underground stream of this area according to survey of main water system and caves except in upper stream of Big Fall. Concerning upper stream of Big Fall of Fengbei Dong, exploration and survey probably will finish next expedition. Therefore report of this expedition issue only electronic publishing. And after the survey of 2008-2009 we will print and publish the report.
