The feature is named after scientist and explorer Alexander von Humboldt.Together with the neighbouring Sima Martel, it was first spotted in 1961 by pilot Harry Gibson.The sinkhole was descended for the first time in 1974 and more thoroughly explored in 1976. Its volume is 18,000,000 m3 (640,000,000 cu ft), whereas the maximum width at its upper rim is 352 m (1,155 ft) and 502 m (1,647 ft) below.Only 700 metres from the rim of Sima Humboldt there is another enormous sinkhole, Sima Martel.
