Explanation: Get out your red/blue glasses and gaze across a mountainous region informally known as Tartarus Dorsa. This scene sprawls some 300 kilometers (about 180 miles) across the Plutonian landscape. The color anaglyph creates a stereo view by combining parts of two images taken about 14 minutes apart during the New Horizons historic flyby of Pluto last July. Along with shadows near the terminator, or line between Pluto's dim day and night, the 3D perspective emphasizes the alignment of narrow, steep ridges. The region's remarkable bladed landforms typically extend 500 meters high and are 3 to 5 kilometers apart. Referring to a part of Hades in ancient Greek mythology, Tartarus Dorsa borders Tombaugh Regio to the east.

From the distance this image was made, our eyes would perceive no 3D structure at all. The greater the separation between the images, the more exaggerated the 3D effect. It's not a question of "correct" positioning, simply a choice made by the image author (and also determined, no doubt, by the raw images which are available).
<<This is the most detailed view of Pluto’s terrain you’ll see for a very long time. This mosaic strip – extending across the hemisphere that faced the New Horizons spacecraft as it flew past Pluto on July 14, 2015 – now includes all of the highest-resolution images taken by the NASA probe. With a resolution of about 80 meters per pixel, the mosaic affords New Horizons scientists and the public the best opportunity to examine the fine details of the various types of terrain on Pluto, and determine the processes that formed and shaped them.
The width of the strip ranges from more than 90 kilometers at its northern end to about 75 kilometers at its southern point. The pictures in the mosaic were obtained by New Horizons’ Long Range Reconnaissance Imager (LORRI) approximately 15,850 kilometers from Pluto, shortly before New Horizons’ closest approach.
