This image, taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express spacecraft, shows the regions of Granicus Valles and Tinjar Valles, which may have been formed partly through the action of subsurface water, due to a process known as sapping. The HRSC obtained these images on 14 February 2005 during orbit 1383 at a ground resolution of approximately 23.7 metres per pixel. The images have been rotated 90 degrees counter-clockwise, so that North is to the left. Both channel systems evolve from a single main channel entering the image scene from southeast (upper right), exhibiting an approximate width of 3 km and extending 300 m below the surrounding terrain at maximum.

This map shows the regions of Granicus Valles and Tinjar Valles, lying at approximately 26.8° North and 135.7° East. The northwest-aligned Granicus Valles and Tinjar Valles are part of the Utopia-Planitia region, an area thought to be covered by a layer of lava that flowed from the northwest flanks of Elysium Mons into the Utopia-Planitia Basin.

This 3D anaglyph is based on data captured by the High-Resolution Stereo Camera (HRSC) onboard the ESA spacecraft Mars Express. Accompanying colour scenes were derived from the three HRSC colour channels and the nadir channel, while this anaglyph image was calculated from the nadir and one stereo channel.
