Sima Martel and Sima Humboldt are two huge sinkholes that were discovered in 1961. They are located on the Sarisarinama Tepui, a remote 2,500-meter tall flat-topped mountain already known to host unique species.

This sinkhole is a lost world embedded into another. | Unsolved Mysteries & Paranormal Activities
