Uranius Mons (Mars)

This feature is named after an earlier feature.

The name "Uranius Patera" now refers only to the volcano's central caldera. It belongs to the Uranius group of volcanoes in the Tharsis area. The sides consist of radial lava flows; the large caldera is elongated in the southwestern direction. (wikipedia entry)

A mons is a mountain. On Mars they are named after the nearest named albedo feature on the Schiaparelli or Antoniadi maps.
