The Shark

The slanted rock shown here was named The Shark. The Shark, Half Dome, and Moe are all rocks which were slanted. The slant seemed to show that water once flowed once in the area, and deposited a bunch of boulders. The Shark was a bright rock, and it also may be a special kind of igneous rock called basalt.

A close look at The Shark provided scientists with evidence that there may have been flowing water in the region long ago. Other evidence of the past existence of flowing water came in the form of rounded pebbles, and conglomerates. These bits of evidence helped scientists figure out the possible origin of the rocks. Proving the existence of flowing water is part of the overall results of the Mars Pathfinder mission.
