Alba Mons (Mars)

This feature is named after an earlier feature.

Alba Mons is an immense, low-lying volcano located in the northern Tharsis region of the planet Mars. It is the largest volcano on Mars in terms of area, with volcanic flow fields that extend for at least 1,350 km from its summit. Although the volcano has a span comparable to that of the United States, it reaches an elevation of only 6.8 km at its highest point. This is about one-third the height of Olympus Mons, the tallest volcano on the planet. (wikipedia entry)

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