Death Valley


At the split cinder cone, I was struck by the specific events that coincided to form such an odd geologic feature. It is obvious that this is a strike-slip fault based on the current placement of the cone. But this prompts me to wonder about the fault itself, I would like to know more about the time it took for move this area. Is the fault still active today? Could its movement cause another basaltic eruption and eventually form another cinder cone? I would like to have more information about the past fault movements.

The Artist’s Drive formation is also very intriguing. This prompts me to ask questions about the water flow through the rock bulges, I would like to know more the erosion caused by flowing water in contrast to the deposited sediment from water flow. Do they even out? Meaning that no more sediment is eroded away than deposited, and does this make the area somewhat resistant to typical water erosion? What changes can be observed with the color of the formation from deposited sediment? I would like to observe the color changes in the rock overtime and I would also like to see the recorded amount of erosion that had occurred overtime.

After looking at Mosaic Canyon, I would like to know more about the rock deformation. In the pictures, it appears as if the rock had been folded by a form of compression. What moved this rock and caused it to fold? Is that force still working today?  It also appears that the rock in some parts is layered, meaning it was deposited and then a downward force compressed it together, I would like to know the ages of these layers. That way the times and frequency of flooding could be understood. I would like to know more about the layer ages and the approximate times of flooding.
