To be clear, yes, we can see everything from Google Earth or other satellite imagery, but that doesn't mean we can explore it. GE can't see into forests, canyons and caves.

Has every mountain been scaled? Has every ocean depth been mapped? Has every jungle been navigated?

Basically, the question is, is there any part of our planet left to explore? To put your foot on a rock and shove a flag in the ground and name it whatever you please. What are the main areas left for exploration that someone might want to try and do. Clearly not every square foot of the Sahara has been navigated, but that's a bit harder than say, a North American forest.

    The deep ocean and many cave systems, this is part of the thrill of spelunking apparently. Nov 2 '11 at 7:19

    I think we're risking branching out too far but let's see ... It's never a bad thing to test the boundaries but as the site's leader people will be more reluctant to vote you down of course. Nov 2 '11 at 7:39

    No one knows for sure where those places are, and what secrets they hold, but one thing is known: Mark Jenkins is going to find them. Simply put, he's broken more secrets in the last decade than many explorers did their whole life. Follow his lead, and you'll know where to look.

    @Dirty-flow: I don't know if this question belongs here, but it's definitely not GIS. GIS is about working with geographical data on computers. May 28 '15 at 11:46

The ocean floor.

Any other unexplored spots pale in comparison with about 75% of the planet's surface covered by oceans, of which hardly anything deeper than 100m has been meaningfully explored. There are literally millions of square kilometers about which we know nothing except a very coarse-grained depth profile. There could be a hundred sunken Atlantises and thousands of bizarre bottom-dwelling species nobody has ever seen.

  • Not really terribly accessible to the average explorer without hundreds of thousands of $s, but I get your point.

Roads, pretty much by definition, are mapped somewhere. In northern Ontario there are "logging roads" which were made by the logging companies and don't have the same legality as a road made by government (municipal or otherwise.) But if someone got out some heavy equipment and made a road, there is a map somewhere that shows it. It just might not be a publicly accessible map (or road for that matter.)

Rivers, on the other hand, are not made. And they most definitely can allow you to travel somewhere that was not mapped or known. As recently as 2012 a canoeist discovered a 40 foot waterfall (by going over it) on an uncharted river. Canada's north is rich in that sort of thing; doubtless there are other parts of the world that have it too.


Maybe the next Movile cave, which has been separated from the rest of the world for millions years, until 1986?

Or some remote mountains on the south of Chile: Access is difficult and weather is not friendly. I would not be surprised if some have not been climbed yet.


For the mountain has not been explored yet :


The Gamburtsev Mountain Range (also known as the Gamburtsev Subglacial Mountains) is a subglacial mountain range located in Eastern Antarctica, near Dome A.The range was discovered by the 3rd Soviet Antarctic.

It is approximately 1,200 kilometres (750 mi) long, and the mountains are believed to be about 2,700 metres (8,900 ft) high, although they are completely covered by over 600 metres (2,000 ft) of ice and snow. The Gamburtsev Mountain Range is currently believed to be about the same size as the European Alps.

Try Egypt, or the Sahara at large. in 2012 a WWII british airplane was found 70 years after it made an emergency landing in Egypt. The poor pilot made it safely on to the ground, the sad part is that it took 70 years before some one else came along. It was still in pristine condition. In that time simply nobody passed that location. Who knows what still lies out there.

Many Parts of New Guinea have not been reached yet because of extensive forestation:

The uncontacted tribes in the Brazilian Amazon are fascinating! Here is a link to a video clip of a flyover, where you can peek into the lives people who have never been contacted before!

    A video of an unexplored land, great!

    Beside the obvious ethnocentric bias, “uncontacted” is a bit of misnomer. At least, it is debated. Those are people who actively avoid contact, possibly because their culture had some bad experience with it decades or centuries ago.

    The Amazon is so huge that only a very few people have the bravery to enter in deep rainforest without the brazilian army. There is a guy who challenged the Amazon Rainforest and won. He is Ed Stafford. Other explorer, like Percy Fawcett lost.

Apparently some of the Venezuelan Tepui remain unexplored. Many of them are part of a national park however, and you might need permits to vist (and you couldn't leave a flag there!)


In addition to what Kate said about rivers, it's worth noting that current mapping of even oceans is subject to change, error or re-writing.

Late last year a team of scientists was in the South Pacific doing a geographical survey of Sandy Island, 20 miles long and 5 miles wide.

There was just one problem. The island doesn't exist. It was on Google maps and other sources showed it but when they turned up - the water depth was 1400m!

A relevant quote from a Google spokesperson sums it up nicely:

"One of the exciting things about maps and geography is that the world is a constantly changing place and keeping on top of these changes is a never-ending endeavour".

    This was a case of charted non-land rather than a case of non-charted land (-: Aug 10 '13 at 2:20

    Yes, but my point is if that can happen, odds are the inverse can too :)

I would be very surprised if the majority of either Antarctica or Greenland has ever been touched by a human on the ground. On the other hand, there's effectively nothing to see in such locations, either.



  • 1,083,206,916,846 km3. volume
  • 510,072,000 km² surface area

There is a huge difference in area to explore under the surface. As well, Google Earth can't see underground. Granted, it could be hard and not interesting to dig a hole. The idea of "Journey to the Center of the Earth" comes to mind. You could spend generations digging, or you may enter and never come out.

  • Cool! Where do those #s come from?

Maybe Gobi Desert is one of them where human try to go but do not return.


Desert. Not only the Sahara or Gobi as mentioned but in general all deserts. I remember this radio talk and that guy, P.Frey, claims he is the only person to have crossed the Sahara in the East-West direction. Mostly because people living in the desert actually live in small areas and never really cross it.

In general deserts are by definition not places with settlements and nobody visits them on a regular basis. There is little knowledge about them.


A lot of forest areas in India, south Asia or Africa might be be unexplored. GE can give an aerial view but it is very difficult to determine what is actually going underneath the forestation. These areas might be inhabited too.


Sơn Đoòng Cave was only discovered in 1991 and has the largest known cavern in the world.

It has only been open to tourists since 2013 and only small numbers at that.

When you consider that this cave was unknown until so recently, it's safe to say there are many more caves in inhospitable parts of the world that have yet to be discovered (or maybe rediscovered). Maybe even some that are bigger than Sơn Đoòng.

Jungles, mountain ranges and remote islands are all good candidates for exploring. Remote islands with mountainous jungles combine all these things and make for excellent candidates (ie Papua)

And of course the ocean floor is the largest of all unexplored territories.
