Long shadows are cast by a low Sun across this rugged looking terrain. Captured by New Horizons, the scene is found just south of the southern tip Sputnik Planum, the informally named smooth, bright heart region of Pluto. Centered is a feature provisionally known as Wright Mons, a broad, tall mountain, about 150 kilometers across and 4 kilometers high, with a 56 kilometer wide, deep summit depression. Of course, broad mountains with central craters are found elsewhere in the Solar System, like Mauna Loa on planet Earth and Olympus Mons on Mars. In fact, New Horizons scientists announced the striking similarity of Pluto’s Wright Mons, and nearby Piccard Mons, to large shield volcanoes strongly suggests the two could be giant cryovolcanoes that once erupted molten ice from the interior of the cold, distant world.

長長的陰影在這片崎嶇的地形上投射出來，這是新地平線號（New Horizons）拍攝的場面，位於冥王星（Pluto）南端的蘇必卜尼克平原（Sputnik Planum）附近。中間的特徵是暫時命名為懷特山（Wright Mons）的一座寬廣高聳的山脈，約150公里寬，4公里高，擁有一個56公里寬的深凹頂部。顯然，擁有中央坑的寬廣山脈在太陽系其他地方也可見到，例如地球的馬納羅亞（Mauna Loa）和火星的奧林匹斯山（Olympus Mons）。事實上，新地平線號的科學家宣布，冥王星的懷特山和附近的皮卡德山（Piccard Mons）有著驚人的相似之處，這表明這兩座山可能是巨型冷火山，曾經從這顆寒冷遙遠的星球的內部噴發出熔融冰。
