Geneses of Jingpo Lake, Diaoshuilou Waterfall and Heilong Pool
When
a volcano lying tens of kilometers from the west
of Jingpo Lake erupted, the turbulent and hot lava flow run
eastward into Mudan River along the valley and blocked the Mudan River channel like a dam, which made the water level rise and the water acreage enlarge,
thus led to formation of the largest volcanic dammed lake in our country – Jingpo Lake. The
surface of rushing and rolling lava flow rapidly cooled down and solidified to
hard crust, while the lava within the crust still remains underflow forward in
the form of liquid. When no subsequent lava supplied,
the flowing lava beneath the hardened surface would gradually drain off, so
that a cave like tunnel was formed in the lava interior, i.e. lava tunnel.
And the lava tunnel is easy to collapse due to the cracks
on the roof formed in cooling and solidification. Here is the landscape
caused by the collapsing of large lava tunnel. The
water of Jingpo Lake flows over the cliff where
the lava tunnel collapsed, and forms the largest
basalt waterfall in the world – Diaoshuilou Waterfall. The plunging water gathers at the collapsing place, and forms the rough Heilong Pool.
