Earth from Space: Indus River Valley
This Envisat image shows the various types of terrain and vegetation cover of the Indus River Valley in the Sindh Province of Pakistan.
The Indus River, which originates in Tibet, is shown winding south from the top of the image through the plentiful green vegetation, which lies in stark contrast to the rugged limestone hills of the Kirthar Range to the west and the Thar Desert to the east.
Thar Desert, located partly in Pakistan and partly in India, is the world’s seventh largest desert. During the January to June dry season, wind-driven sandstorms rising in the Thar are a common occurrence.

In the 1920s, archaeologists excavated the Indus Valley cities of Harappa and Mohenjo-Daro and discovered an ancient civilisation, referred to as the Indus Valley Civilisation, had developed along the Indus River.
These ancient cities, which had drains, sewers and latrines, were carefully planned and laid out on the shores of the Indus. Archaeologists were able to determine that the river had flooded and destroyed the cities several times and each time they were rebuilt in exactly the same way.
