They provide a wonderful glimpse into what Mars was like in the earliest part of its history, ... It was a violent place. It was a place where meteorite impacts were happening frequently. It was a place where there volcanic explosions happening frequently. Hot stuff was raining from the skies. There was water. When rocks were deposited, water would flow through those rocks and change their chemistry. This is a glimpse into the ancient past of Mars.

driving hang
We're also really getting the hang of driving in this terrain.
changes compelling consider evidence flowing surface water
We've got some evidence, I think, of water flowing through the rocks, and changes in chemistry, I don't think we have what any of us would consider compelling evidence for surface water yet.
