Mount Roraima

Mount Roraima is a giant flat-topped mountain, or mesa, in the Pakaraima Mountains of the Guiana Highlands. Encyclopaedia Britannica places it at the meeting point of Brazil, Venezuela and Guyana, and gives its height as 2,772 metres. The mountain's tabletop summit and steep sides are characteristic of tepuis, the table-mountain formations found across the region.

Roraima is part of a broader landscape of sandstone table mountains. UNESCO describes Canaima National Park in southeastern Venezuela as a landscape where tepui formations cover roughly 65 percent of the park; it highlights their geological interest and distinctive biogeological character. The World Wildlife Fund's reference account on the Tepui ecoregion describes isolated sandstone plateaus, high escarpments and varied summit vegetation, while noting that the ecoregion page is retained for historical reference and may be out of date.

Britannica identifies Mount Roraima as a source of rivers in Guyana and of rivers in the Amazon and Orinoco systems. Its isolated high summit belongs to the broader tepui environment, where conditions and plant communities can differ from those of surrounding lowlands. Detailed biodiversity descriptions apply to the tepui region as a whole and should not automatically be treated as a complete inventory of Mount Roraima itself.

The mountain is also known as Cerro Roraima and Monte Roraima. The word tepui comes from the Pemón language, as noted in the WWF reference account. Roraima lies in a region with Indigenous communities and cultural traditions; geographic descriptions should be read alongside the knowledge and perspectives of those communities.
