Today, as human civilization spreads across continents and oceans
and has long ventured into the vast universe,
this place has retained its most primitive appearance.
Across tens of thousands of square kilometers of land,
this is the most ordinary scene on this earth.

It is the Altun Mountains National Nature Reserve,
one of the harshest regions in terms of natural environment,
and was once the least studied blank spot
in China and even the world.
What exactly made it such a place,
and what has shaped its present form?
A narrow mountain range sandwiched between the Kunlun Mountains and the Qilian Mountains,
stretching across the borders of Xinjiang, Qinghai, and Gansu provinces,
but located south of this mountain range
is the Altun Mountains National Nature Reserve
(hereinafter referred to as the Altun Mountains).
However, there is no geographical connection.
The main body of the reserve lies in the largest basin of the Kunlun Mountains.
Its total area reaches up to 45,000 square kilometers.
(Please view horizontally. The Altun Mountains National Nature Reserve, though sharing its name with the Altun Mountains, has no geographical connection to the mountain range and is entirely independent of it. Map by Zhang Songnan & Han Qing/Planet Research Institute.)
National nature reserves such as Hoh Xil, Lop Nur, and Changtang
are collectively known as China's four major uninhabited zones by the public.
(Distribution map of the four major nature reserves. Map by Zhang Songnan & Han Qing/Planet Research Institute.)
Some are infamous for tragic poaching incidents,
while others attract the public with their mysterious ancient civilizations.
No extra ink in the world is spent to write about it,
nor are there complete film works documenting it.
But this does not mean it was born mediocre.
This is the almost forgotten corner—
(Please view horizontally. A herd of wild yaks traverses the endless desert, appearing tiny amidst the vast sands. Photographer: Tao Shu.)
Its average elevation exceeds 4,000 meters,
but warm moments are extremely fleeting.
Thus, its annual average temperature is only 2°C,
dropping below -30°C in the coldest winter periods.

The despair of the Altun Mountains does not end here.
It is encircled by even higher mountains,
such as the Qimantag Mountains, which rise over 5,000 meters.
(The Qimantag Mountains are a range in the northeastern part of the reserve, with only a corner shown in the image below; photographer: Hao Pei)
Peaks such as Muztagh, standing at nearly 7,000 meters in elevation
(The towering and massive Muztagh Peak; photographer: Wen Xinghua)
Surrounded by mountains that block moisture
It grows even drier in this arid region
The warm, humid air currents from the Bay of Bengal
After traveling nearly 2,000 kilometers
Finally become a raindrop drifting over the Altun Mountains
(Moist clouds among the Qimantag Mountains; photographer: Jin Lei)
But in this place closest to the sky
It receives up to 2,900 hours of sunlight annually
Resulting in an evaporation rate as high as 2,500 millimeters
Thus, an extremely arid zone is born
(Cracked earth caused by the dry climate; photographer: Shen Jiuquan)
It also fuels the rise of another force
Yet the fierce winds bring no additional moisture to the Altun Mountains
Instead, they carry countless grains of sand
(Pyramid-shaped dunes as tall as mountains; photographer: Tao Shu)
Crescent-shaped dunes that indicate wind direction
(Crescent-shaped dunes; photographer: Tao Shu)
forming chains of dunes like waves in a sandy sea
often extending for tens of meters or even several kilometers
(Winding chains of dunes, photographer @ Wang Wei)
(Distribution of deserts in the Altun Mountains National Nature Reserve, mapped by @ Zhang Songnan & Han Qing/Planet Research Institute)
It is also the highest-altitude desert in the world
Connecting desolation is an even vaster desolation
Beyond solitude lurks an even deeper solitude
(Kumkuli Desert, photographer @ Dreamscape)
Is this plateau, shrouded in extreme cold, hypoxia, drought, and sandstorms, destined only for despair devoid of life?
When we observe this region from satellite maps
areas that should be extremely arid
water systems scattered in different corners
(Distribution of water systems in the Altun Mountains National Nature Reserve, mapped by @ Zhang Songnan & Han Qing/Planet Research Institute)
If we take a closer look at some of these lakes
their clarity is even more astonishing
(Please view horizontally, panoramic view of Rabbit Lake, photographer @ Hao Pei)
Encircled by a ring of high mountains around the Altun Mountains
in areas with elevations exceeding 5,500 meters
eventually forming 388 glaciers
(Glaciers developed on Bukadaban Peak, areas above 5,500 meters in the reserve are permanently snow-covered, photographer @ Bu Qiong)
Among them, the Muztagh Peak at the southwestern corner of the Altun Mountains
is also the region richest in modern glaciers
It boasts glaciers such as Binglinchuan, Linglong, and Yueya
totaling 116 glaciers of various sizes
with a combined area exceeding 680 square kilometers
(Glaciers on Muztagh Peak, photographer: Wen Xinghua)
All the glaciers scattered around the Altun Mountains
are equivalent to nearly 70 billion cubic meters of freshwater reserves
enough to meet Guangzhou's domestic water demand for nearly 7 years
This is a glimmer of hope for the Altun Mountains
However, the streams formed by melting glaciers are extremely fragile
and still insufficient to combat the boundless drought
they gain unstoppable momentum
(Please view horizontally, rivers breaking through the desert in the Altun Mountains, photographer: Li Xueliang)
Converging and intertwining across the vast wilderness
(Braided rivers, photographer: Zhang Lei)
They can even move freely above and below ground
Some seep underground, flowing silently as hidden currents
(Springs resembling animal eyes in the Kumukuli Desert, photographer: Wang Hanbing)
In the low-lying areas enclosed by mountains
as well as numerous scattered small lakes
They not only nourish the arid land
but also become the brightest embellishments on the vast wilderness
(An unnamed lake in the Kumukuli Desert, photographer: Shen Jiuquan)
Ayak Kumuk Lake in the northern part of the reserve

As long as the hundreds of surrounding glaciers do not vanish
this hope will continue to irrigate the land endlessly
But in this wilderness fraught with challenges
it is still not enough to create a thriving and enduring land of life
All creatures must rely on their unique skills
and can no longer adapt to such dry and cold conditions
Thus, there are no lush forests in the Altun Mountains
yet this place is filled with a different kind of vitality
(Nitraria, photographer: Jiang Hong)
However, these survival skills honed in adversity
With the dramatic uplift of the Tibetan Plateau
have also profoundly impacted all life that once thrived here
Some of them scattered in search of new homes
while others headed straight for extinction
Most of the flora and fauna living here today
gradually diverged in appearance, organs, and genes
from their ancestors
before finally finding a foothold on this plateau
(Lush marsh horsetail in the waters of Lake Yixiekepati, photographer @ Hao Pei)
In the desert areas far from water sources
especially the vast saline-alkali lands left after water evaporation
but some hardier plant communities refuse to surrender
(Vegetation growing in arid saline-alkali soil, photographer @ Li Xueliang)
In places with strong winds, drought, and poor soil
plants can still rely on creeping growth
to cleverly evade these survival challenges
(Delicate cushion-shaped Androsace tapete, photographer @ Jiang Hong)
Meanwhile, the unseen extensive root systems underground
also help many plants survive droughts and other hardships
such as the vibrant-flowered Iris lactea
(Iris lactea blooming between the Gobi and snow-capped mountains, photographer @ Jiang Hong)
But there is one skill all plants must master
Even during the warmest hours of each day, they strive to grow
Only in this way can they survive in this harsh land
Oases with vastly different appearances and vibrant life
(Please view horizontally, wetlands by Lake Yixiekepati, photographer @ Hao Pei)
It is also home to approximately 200 species of wild animals
And the ways these animals survive adversity
(Tibetan antelopes at the foot of snow-capped mountains, photographer @ Jiang Hong)
Have evolved warmer fur than their ancestors
(Wild yaks running on snow, photographer @ Guo Xilai)
They possess larger and uniquely structured nasal cavities
As well as thicker blood vessels and larger hearts
(Comparison between Tibetan antelopes and goats; "Tibetan antelope" is the formal name, illustration @ Hanqing/Planet Research Institute)
While gentle Tibetan antelopes are seen as prey by many predators
They rely on their "wind-like" speed
Tibetan antelopes can reach ultra-high speeds of 80-100 km/h
Without needing to stop for traffic lights
They could circle Beijing's Fourth Ring Road (65.3 km) in one go
(Tibetan antelopes running under snow-capped mountains, photographer @ Jiang Hong)
Besides escaping predators by running
Tibetan antelopes also retain the habit of regular migration
This also allows them to reproduce more safely
They will collectively migrate to fixed breeding grounds
They return once again to areas with more abundant water and grass
Many stumbling Tibetan antelope calves appear among the herd
This is also on this harsh wilderness
(There are also a few calves in the Tibetan antelope herd, photographer @ Wang Peng)
They have shorter tracheas and more developed hearts and lungs
Thus enabling them to cope more easily with oxygen-deficient environments
(Comparison of body structures between wild yaks and water buffaloes, illustration by @ Hanqing/Planet Research Institute)
These enhanced physical adaptations
Not only allow them to adapt effortlessly to the plateau environment
Even against highly ferocious animals like wolves and brown bears
("Yak" staring intently, photographer @ Hua Shi)
Their traces are scattered across different corners of the reserve
Or crossing deserts in large groups
(Please view horizontally, wild yaks traversing the desert, a beauty where vitality and desolation coexist, photographer @ Tao Shu)
(A lone wild yak walks to the edge of a sand spring, photographer @ Wen Xinghua)
In this vast and free expanse of land
It accommodates approximately 12,000 wild yaks
(Please view horizontally, a "convoy" of wild yaks on the grassland, photographer @ Jiang Hong)
(Please view horizontally, a "caravan" of Tibetan antelopes in the snow, photographer@Jiang Hong)
(Please view horizontally, a "caravan" of wild Tibetan donkeys in the wilderness, photographer@Wang Bin)

The sometimes fierce, sometimes adorable Upland Buzzard (kuáng), and more
(A curious Upland Buzzard tilting its head, photographer@Hao Pei)
Though most lack the vibrant colors and delicate forms of tropical flora and fauna
They are all warriors and victors against the adversities of the plateau
And the greatest hope in this wilderness
(Please view horizontally, a herd of wild yaks climbing a towering dune beside a large lake, photographer@Lu Quanguo)
The hope of the Altun Mountains has been fully revealed
Yet it never fades because of its existence
Whenever a rainbow arches across the desert and clouds
Whenever sunlight pours unreservedly onto the sacred peaks of snow-capped mountains
Whenever creatures gallop joyfully across the boundless wilderness
The dawn of hope once again illuminates the shadows of despair
Perhaps something we can never personally experience
也许就是我们永远无法亲自体会的

Not all precipitation in the Altun Mountains region comes from the warm and humid air currents blowing from the Bay of Bengal.
