Diverging Processes Within Las Vegas Valley.

   Let's navigate to Las Vegas. Set the map to "Terrain" mode. See the part of Las Vegas Valley between North-West of Las Vegas and Indian Springs which is further North-West approx 50km. Would not north-eastern mountains of this part of the valley fit south-western mountains if the part of the valley were cut off the map? I'd say, yes. If the depths of the mountains were found of different stuff and age than the depths of the valley floor, then the mountains were diverging. The valley's floor, I'd expect to be of magmatic nature that a divergent boundary usually consist of. The mountains I'd expect to be gathered of chunks of older oceanic crust and therefore even at the depths they should show all the usual oceanic floor features.
