Summary: The Curiosity has come to a conglomerate of rocks which gives evidence for water on Mars. The main signs are small rocks that have broken off from a huge rock and have been weathered smooth, like rocks found in a river bed here on Earth. Curiosity will continue to investigate these rocks in hopes of being able to determine the pH level of the water that had passed through this area.
