Cerro Duida

Cerro Duida, known as Yennamadi by the Ye'kuana, is a very large tepui in Amazonas state, Venezuela. It has an uneven and heavily inclined plateau, rising from highs of around 1,300–1,400 metres (4,300–4,600 ft) in the north and east to a maximum of 2,358 metres (7,736 ft) on its southwestern rim. It has a summit area of 1,089 km2 (420 sq mi) and an estimated slope area of 715 km2 (276 sq mi). At its foot lies the small settlement of La Esmeralda, from which the mountain can be climbed.

Cerro Duida shares a common base with the much smaller (but taller) Cerro Marahuaca, located off its northeastern flank, and together they form the Duida–Marahuaca Massif. Both tepuis are entirely within the bounds of Duida-Marahuaca National Park. Sandwiched between them, a massive ridge known as Cerro Petaca rises to at least 2,700 metres (8,900 ft). The much lower Cerro Huachamacari, derived from a separate base, lies to the northwest of this complex.
