With satellites permanently scanning the planet and with means of transport that allow access to the most inaccessible places…

…we may wonder if there are any unexplored places on Earth.

Yet, humans have never set foot on certain regions of the globe!

So what are these places still to be discovered?

Explorers call them gray areas: places we know exist but which have never been explored because they are inaccessible.

South America, for example, still has some primal forests which have never been visited.

In the Amazon forest alone, researchers discover a new animal or plant species every 2 days!

There are also mountains that have never been climbed, such as Gangkhar Puensum, in the Himalayas.

But there’s also a territory still largely unknown, just under our feet.
