COPPER CANYON HIKE IN DEATH VALLEY
This canyon is off-limits and can only be visited under supervision of a park ranger. There are fossils being studied in the area and so they don't want visitors tampering with any of that stuff. Although this video has been available since 2010, many people frown on images and videos like this since they publicize locations which are protected. Notice that violators can be fined up to $5000 or face six months in prison.
