Anaglyph image of the southern part of Phlegra Montes
The stereo capability of the HRSC imaging system makes it possible to create anaglyph images from a combination of the various stereo image channels, which are directed obliquely towards the surface of Mars, and the nadir channel that looks down vertically at Mars. Viewing the image using red/cyan-coloured ‘anaglyph glasses’ creates a three-dimensional impression of the landscape.
This enables subtle differences in altitude to be easily perceived, including wrinkle ridges that were created when the lava flows in the volcanic plain west of the mountains (upper right third of image) cooled, or bulges and remnants of landslides at the foot of the Phlegra Montes mountain chain.
