abundant alteration beneath climbing core deep drill drilling environment equivalent evidence figure finding good helpful layers rocks sequence top understanding views water
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.

We are also interested in looking at the soils and rocks exposed during impact and making imaging and other measurements of these materials. This latter set of experiments will allow us to probe subsurface characteristics.

It was having a tough time because of the loose nature of the material.
