The Jiuzhaigou Valley is an enchanted forest, a harmony of nature especially remarkable during the autumn months."
The splendor of forests and lakes, the Zhujiaogou Valley.
00:00:00
A remarkable landscape of lakes, large and small,
00:00:07
stretches out in the Zhujiaogou Valley in Sichuan Province, in China.
00:00:11
There are over a hundred lakes in the Minshan Range.
00:00:18
The water flows through the many lakes and gushes out at the Nuzhulong Waterfall,
00:00:24
the largest in Zhujiaogou.
00:00:29
There is an extraordinary spectacle here. Water flows through the forest.
00:00:35
The trees cling at the roots resisting the flow of water.
00:00:42
This landscape was formed over 2,500 million years ago
00:00:48
as the ocean bed rose to an elevation in excess of 4,000 meters.
00:00:52
The advance and retreat of glaciers millions of years ago eroded the mountain.
00:00:59
Rock and earth deposits were left behind.
00:01:05
The valley would later be filled with groundwater.
00:01:09
Formerly at the bottom of the ocean, the water is highly calcareous.
00:01:12
Over time, a series of stepped lakes developed.
00:01:19
The water is so transparent,
00:01:26
it's possible to see the reflections of the ripples at the bottom of the lake.
00:01:28
It's amazingly white in color because of the calcium.
00:01:32
This dead tree is what is called the tufa, created by calcareous substance
00:01:38
accumulating on its trunk and branches.
00:01:43
It's as if there is a huge dragon lying across the bottom of the lake.
00:01:52
It is, in fact, a milky white dam of calcium underwater.
00:01:56
The calcium plays an important role in the forested cover between the lakes.
00:02:03
It's not easy for seeds to take root in the fast-flowing waters.
00:02:07
And this is where the tufa dams play a role.
00:02:11
They contain numerous tiny holes which catch seeds, which eventually take root.
00:02:14
Vegetation flourishes.
00:02:21
The Jiujiagou Valley is an enchanted forest,
00:02:25
a harmony of nature especially remarkable during the autumn months.
