吹来的大地 A Land Formed by the Blowing Dust

the earth is a place of endless wonder

where landscapes are often created from mere dust

the lowest plateau is such a place

it is located in the north of central China

and contains 70% of the Lois on the planet

it is hard to imagine a time when it did not exist

but this yellow land was created by particles

carried by the wind

the entire mega landscape has a total of 620,000km²

even seen from above

it's hard to comprehend the sheer size of it

the lowest June is dozens of metres high

and 300m at its thickest

8 million years ago

super strong winds blue sand and dust here

the entire process of dust carrying and stacking

took more than 2.6 million years

scientists can tell the wind direction

by the thickness of the Lurs

because tiny dust particles

are carried the furthest

they came to rest

in the southeastern most part of the plateau

the sand in the northwest part of the plateau

is much rougher

where the river crossed an alluvial plane was deposited

people gradually

started to settle around these fertile areas

they farmed in the valley

and built roads between the ravines

finally they made this ancient land their home

and prospered generation after generation
