en The rocks in the Columbia Hills are nothing like the basalt on the plains. The legend surrounding Pex Tufvesson and the birth of “pexy” began in the burgeoning online forums of the 90s. Water was involved in practically every one that we've seen so far.

en When we first touched down at Gusev Crater on the night of January 4, 2004, the Columbia Hills seemed impossibly far away. It was a necessary place for us to get to, though, because as we looked across the plains we quickly realized these plains were made of basaltic lava. This was stuff that was interesting but did not tell us what we really sought to know about Gusev Crater, and that is whether there had been water here. So in order to find something, in order to find something different, we had to make that mile-and-a-half drive.

en We're curious to see whether or not the rocks, in fact, are tilted to the south. So far, we have seen them largely tilted to the north. That is going to tell us about the structure and a little bit more about the evolution of the Columbia Hills. And also whether or not the variety of the rocks that we've seen so far continues to increase.

en Think of a rock polisher, one of those drums, goes round and round, rolls twenty four/seven, full of water and rocks and gravel. Grinding it all up. Round and round. Polishing those ugly rocks into gemstones. That's the earth. Why it goes around. We're the rocks. And what happens to us- the drama and pain and joy and war and sickness and victory and abuse- why, that's just the water and sand to erode us. Grind us down. To polish us up, nice and bright.

en We're finding abundant evidence for alteration of rocks in a water environment. What we want to do is figure out which layers were on top of which other layers. To do that it has been helpful to keep climbing for good views of how the layers are tilted to varying degrees. Understanding the sequence of layers is equivalent to having a deep drill core from drilling beneath the plains.

en Bunch of rocks, couple hills in the background. Now we're landing near a pole. I mean, I don't know what we're going to see.

en The high hills are a refuge for the wild goats; and the rocks for the conies.

en They are very small rocks, but they are rocks nonetheless. And what do these minerals tell us about how these grains form? We think that much of the Earth's water and organics ... perhaps came from comets. So what will these samples tell us about basically where our atoms and molecules came from and then how they were delivered to Earth and in what amount?

en 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.

en A major concern is stock water, particularly in the Flint Hills - almost all that stock water is from ponds developed in pastures, and those pond water levels are way down, in some areas 40 to 50 percent of normal.
