Here's the breakdown:
* Transylvania is a historical region in central Romania, bordered by the Carpathian Mountains.
* The Olt River flows through the Carpathian Mountains, passing through Transylvania but also extending into other regions of Romania.
So, the Olt River is important to Transylvania, but it's not *exclusively* found there.
To clarify, some of the major geographical features of Transylvania include:
* The Carpathian Mountains: Surrounding the region and defining its borders.
* The Transylvanian Plateau: A large plateau within the region.
* The Someș River: A major river that flows through Transylvania.
* The Mureș River: Another significant river flowing through the region.
