Mars - Viking 1 Orbiter

Parana Valles drainage system in Margaritifer Sinus, Mars

Mars
This Viking 1 Orbiter image shows the Parana Valles, a digitate valley network in the Margaritifer Sinus region of Mars. These networks look similar to river drainage networks on Earth, and were presumably formed by running water sometime in Mars' past. This image is about 250 km across. North is at ~10:30.
