New research supports the long-held hypothesis that the Grand Canyon is as young as six million years. That’s what geologists originally believed before a different study claimed it was tens of millions of years older.
The study was conducted by geologists at Arizona State University. It compares the western Grand Canyon with the Grand Wash Cliffs. It found that the canyon is steeper than the cliffs, which suggests erosion started more recently.

Federal wildlife officials are monitoring a wolf-like animal roaming forest land near the North Rim of the Grand Canyon. As Arizona Public Radio’s Ryan Heinsius reports, if confirmed to be a gray wolf, it would be the first such animal seen in the area in 70 years.
Every experienced hiker, river runner and climber I know has made mistakes of one sort or another. Usually it takes a string of them to get into serious trouble, but even then some people manage to pull it off. Whether they do so on skill alone or pure luck is never clear. I once found myself deep in the Grand Canyon clinging to the side of a cliff, unable to move up or down.
Northern Arizona is full of river runners, many of whom take their dogs downriver with them. Whether it's the Verde or the Salt River, many a mutt has gone along for the ride.
