The Chimantá Massif is a highly fragmented complex of tepuis in Bolívar state, Venezuela. The massif comprises around 11 tepuis[1] and has a total summit area of 615sqkm and an estimated slope area of 915sqkm.[2] It is divided in two by the Río Tírica, with the northern section being both larger and higher. The massif is notable for its high species richness and for its varied habitat types. It reaches an elevation of 2698m (8,852feet)[3] on its highest peak, Murey-tepui (also known as Eruoda-tepui). The massif is situated entirely within the bounds of Canaima National Park.[4] It hosts extensive cave systems, including the world's largest known quartzite cave, Cueva Charles Brewer, named after discoverer Charles Brewer-Carías.[5] [6] [7] The processes behind their speleogenesis are the subject of some debate.[8] [9] [10]

The isolated southern peaks of Angasima-tepui and Upuigma-tepui are sometimes considered part of the Chimantá Massif.[11]

Tepuis

The major tepuis of the northern and southern parts of the Chimantá Massif are listed below. Coordinates given correspond to the approximate centre points of the tepui summit plateaus. Unless otherwise indicated, all information in the tables is sourced from Flora of the Venezuelan Guayana.
