Random Riddle: 4-17-2015

Sometimes this area is visible,
But more often than not it’s intangible.
Countries have disputed these spaces,
Drawn treaties to dictate their extent.

Some people are said to have none,
Not knowing where to find them.

They can be found in nature,
Where water meets with land.

It is also a peak of Nevada,
The highest in that land.

So find me now if you can,
In the place between the beginning and the end.
