Desolate, dry, temperature extremes are found here.
Scientists say it once may have been wet with freely available liquid water.
Indeed, it wasn’t always like this.
You can still find carvings of giraffes twenty feet high, etched in stone serveral thousand years ago, in the deep desert. Like this one.
The desert developed quite quickly according to modern research, and may have been instrumental in humans settling the Nile Valley around 4000 years ago. Even today, you can always clearly spot the Nile.
While we are here we need to visit an ancient necropolis. I had always wondered why they built all that stuff out in the desert. It turns out the desert came to them.
You can see the ancient city in black and white and how the sands from the Sahara are encroaching. The pyramids do not fear time. How long do you think that aluminum siding on your house going to last?
Eventually even the pyramids will sink beneath the sand.
They have built walls to temporarily keep the encroaching sands at bay.
i need info on sahara

On the last picture there are “walls to temporarily keep the encroaching sands at bay.” Wrong. These are mastabas, ancient tombs about the same age as the pyramids themselves. Also, why keep the sands at bay, facing the city, instead of the desert????
Tore, thanks for your comment, I should have done more research for this brief article.
