Informally named Wright Mons, a broad mountain about 150 kilometers across and 4 kilometers high with a wide, deep summit depression is featured in this inset image captured during the New Horizons flyby of Pluto in July 2015. Of course, broad mountains with summit craters are found elsewhere in the Solar System, like the large shield volcano Mauna Loa on planet Earth or giant Olympus Mons on Mars. New Horizons scientists note the striking similarity of Pluto’s Wright Mons, and nearby Piccard Mons, to large shield volcanoes suggests the two could be giant cryovolcanoes that once erupted molten ice from the interior of the cold, distant world. In fact, found on a frozen dwarf planet Wright Mons could be the largest volcano in the outer Solar System. Since only one impact crater has been identified on its slopes, Wright Mons may well have been active late in Pluto’s history. This highest resolution color image also reveals red material sparsely scattered around the region.

在2015年7月的New Horizons飛越冥王星（Pluto）時，一幅插圖展示了一座非正式命名的山脈——Wright Mons。這座寬廣的山脈直徑約150公里，並且高達4公里，擁有一個寬闊而深邃的山頂凹陷。類似於地球上巨型的盾狀火山Mauna Loa或火星上的奧林帕斯山（Olympus Mons），Wright Mons及其附近的Piccard Mons顯示出與大型盾狀火山的驚人相似性，科學家推測這兩座可能是曾經從這個寒冷、遙遠的世界內部噴發出熔融冰的巨大冷火山（cryovolcanoes）。事實上，Wright Mons可能是外太陽系中最大的火山，因為在其斜坡上只發現到一個隕石坑，這表明它在冥王星的歷史後期可能仍然活躍。這張高解析度的彩色影像也揭示了該區域散布著稀疏的紅色材料。
