Rio Marchenilla
Marchenilla is a small river in the Province of Cadiz, located in Campo de Gibraltar. It is born in the Sierra del Bujeo, at an altitude of about 500 msl, having to save a great slope in its high section. It flows next to the village of Algamasilla and empties at the beach of Getares, south Algeciras. Geologically three sections are distinguished: the head of triassic materials, the middle section of oligocene materials, and the final section of triassic materials.
