Skadi Mons

Skadi Mons was a misidentified geologic feature on Venus. For 31 years it was thought to be the tallest mountain of the planet, located in Maxwell Montes at the center of Ishtar Terra, but further analysis of Venus's topography in 2025 showed that there was no mountain. The name Skadi Mons was approved by the International Astronomical Union in 1994, but was officially dropped and disallowed on 17 December 2025. The name came from Skaði, the norse goddess of skiing. The word means "damage" or "shadow", being related to the name Scandinavia and maybe the underworld.
Skadi Mons was previously thought to be the highest point on Venus's surface, with an altitude of about 10,700 meters above the mean planetary radius. This apparently high altitude led scientists to initially believe that Skadi Mons could have a cooler temperature and lower atmospheric pressure.
