Monoun

Monoun is a locality in Cameroon that is best known for the Monoun meteorite impact crater located nearby. The crater is a circular depression set in tropical lowland terrain, with a rim that remains noticeable in places and a surrounding landscape that bears traces of excavation and disturbance from the impact event.

Geologically, the Monoun crater exhibits characteristics typical of impact structures, including a disrupted bedrock zone around the center. The diameter is commonly reported as roughly one kilometer, though exact figures vary among sources. Erosion and sedimentation have altered parts of the formation, which can complicate interpretation of some details in modern observations.

Discovery and research on the feature began in the late 20th century, when aerial photography and field surveys highlighted the circular morphology. Subsequent investigations confirmed the impact origin and contributed to the broader understanding of meteorite impact processes in equatorial Africa. The site has been cited in discussions of planetary geology and crater formation, helping researchers compare African structures with craters on other continents.

Significance and current status: The Monoun crater is among the better-documented impact features in Africa and has served as a reference point in studies of crater formation, erosion, and terrestrial impact processes. Today, the site remains primarily of scientific interest; researchers may visit for study, while access for general tourism is limited and typically coordinated with local authorities.
