Notes:

Upheaval Dome is an impact structure, the deeply eroded remnants of an impact crater. It is approximately 5 km in diameter and the crater is estimated to be less than 170 million years old (Jurassic or younger.) The crater is clearly visible on the surface as bright brown and black concentric rings.

There were two well-known theories as to the origin of the upheaval. One theory was the upheaval is a salt dome, an anticlinal structure which occurs when a salt diapir is pushed up by the weight of overlying rocks.

The other theory is an eroded impact crater, like the much younger Meteor Crater near Winslow, Arizona. In the 1990s, a team of geologists and seismologists from NASA and the University of Nevada at Reno performed a detailed study that included seismic refraction and rock mapping. The results of this study support themeteorite theory. In 2008, it was announced that shocked quartz was discovered. This confirmed the meteor impact theory because the rocks were subjected to high pressures only possible in an impact or a nuclear explosion.

 

Probably the hardest and hottest hike done. We ran out of water coming back on this windless day. There wasn’t a single cloud in the sky either. What made it worse was that we had to gain elevation to get back to the car. We didn’t do the complete loop as that would have taken even longer and the last half wouldn’t have a great view anyways.

We only ran into 2 people, one of them was running through the area, barely carrying any water…don’t know how he could do that
