Tepui
The
Tepius are table-like
mountains found only in the
Guiana highlands. These geological formations tend to be found as isolated entities rather than in mountain range fashion, which makes them the host of a unique array of
endemic plant and animal species. Some of the most outstanding tepuis are Autana, Neblina (the highest one, on the Venezuelan-Brazil border),
Auyantepui and
Roraima. They are typically composed of
Precambrian sandstone rocks, very hard to climb, that rise abruptly from the jungle, giving rise to spectacular natural scenery.
