RED ROCK TRAIL	SAMPLE #2
CROSSBEDDED SANDSTONE	KEYSTONE THRUST FAULT

This link gives a detailed picture to the geology of the Nevada/California area in general. It is a different Red Rock Canyon than the one outside of Las Vegas, but well worth the visit. There are incredible images of rock outcrops, and the fossils found in the area.

These were magnificent! The trees in the image give you some idea of the size of the now solidified dunes.

This image does not do the fault any justice, but you can tell that something mighty impressive happened here. The hike into the fault was more than we were capable of going in the short time we had at Red Rock. The guide at the information station said that, to a geologist, it was well worth the time and effort. I'll have to take him at his word. "A cap of older gray Paleozoic limestone resting on top of the younger Jurassic period sandstone can be seen [in the image]. . . The occurrence of of older rock on top of younger rock is a result of the Keystone Thrust Fault. About 65 million years ago, compressional forces in the earth's crust were dominant in this region. The older rock was thrust up over the younger rock over a period of thousands, if not millions, of years." Red Rock Canyon newsletter
