Well digging, pulverized rock

This pasty mud is the last material to come out of the well hole. I assume that it's the impeding rock that was ground to dust by the "needle", as shown in the previous post. It's quite possible that the drilling team will hit the vein of water by tomorrow. I'm told that the rest of the operation goes much faster. I hope. The dust on the road is getting to be more than a problem. It's getting to be dangerous.
