Roca Partida is an uninhabited rock island in the eastern Pacific Ocean and at the same time the smallest of the Revillagigedo Islands belonging to Mexico . It is a good 800 km from the Mexican coast and about 107 km west of Socorro , the largest island in this group of islands .
The rocky island, which is distinctively divided into two halves, is 91 m long, 45 m wide and has an area of 0.3 ha (0.003 km²). It represents the tip of an extinct volcano and rises in the Cabeza Conejo , the northwestern peak, up to 34 m from the Pacific, while the Cabeza Sur rises 25 m in the southeast. The isthmus, which is only around 10 m narrow between the two peaks, reaches a saddle height of around six meters.
In analogy to the island of Clarión, there are contradicting information about the discovery of the Roca Partida: The Spanish explorer Ruy López de Villalobos is mentioned, who is said to have sighted the rock for the first time in 1569; José Camacho, on the other hand, is said to have discovered the rock in 1779.
