The Viking 1 Lander sampling arm created a number of deep trenches as part of the surface composition and biology experiments on Mars. The digging tool on the sampling arm (at lower center) could scoop up samples of material and deposit them into the appropriate experiment. Some holes were dug deeper to study soil which was not affected by solar radiation and weathering. The trenches in this ESE looking image are in the "Sandy Flats" area of the landing site at
Chryse Planitia. The boom holding the meteorology sensors is at left. More information can be found at

Date
2009-01-26; original photos were taken 1977-05-26.
I used the original
11d128.blu,
11d128.grn and
11d128.red images from the
NASA Viking image archive, converted them to .png, manually removed the noise and finally merged them into one image (almost matching true color; see
here for the channel mixing process). Except for the conversion, this was all done in Adobe Photoshop CS2. The original files by NASA are in the public domain, and so is this new one.
Other versions
I created this image as a replacement for the image
Viking1mars.jpg (see also:
here) It was created by NASA, but the quality is not very high. Using the original pictures from the lander archive resulted in a higher quality image.
