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.

If asked what's impressive about the Grand Canyon, most visitors probably won't mention a water pipeline. But one of this national park's great engineering feats is the Trans-Canyon Pipeline, which carries half a million gallons of water every day from Roaring Springs down Bright Angel Canyon, past Phantom Ranch and across Silver Bridge.

A major national parks concessionaire has dropped efforts to trademark names of the most popular properties at the Grand Canyon.

Xanterra Parks & Resorts applied for roughly 20 trademarks before its contract to manage South Rim hotels, restaurants and mule rides expired at the end of December. It later won a temporary contract.

The U.S. Patent and Trademark Office now lists some of them as "dead." For others, Xanterra has stated it is abandoning the applications.

Grand Canyon River Outfitters Association

For the first time, a hybrid-electric motor has powered a Colorado River trip through the entire Grand Canyon. As Arizona Public Radio’s Ryan Heinsius reports, the technology is being developed through a partnership between commercial river outfitters and the National Park Service.

The initial public comment period has begun for a series of road improvements on the Kaibab National Forest in the Town of Tusayan. As Arizona Public Radio’s Ryan Heinsius report, if approved it’ll pave the way for a large development project near the South Rim of the Grand Canyon.

  It was a long way from the civilized college town of Ann Arbor, Michigan, to Mexican Hat, Utah, back in the summer of 1937. But Dr. Elzada Clover made the trip.

A botanist at the University of Michigan, she had an ambitious dream to explore the little-known plant life of the Colorado River region. Cacti were her specialty. Where better to find them than the Southwest deserts?

KNAU

Before becoming a national park, the remote western part of the Grand Canyon was a place where a handful of ranchers - with true grit - struggled to earn a living. To make things a little more comfortable, they opened a winter camp deep within the canyon. It was known as "The Hotel" and remains an occasional refuge for hikers. In his latest Grand Canyon Commentary, Scott Thybony tells us about the night he spent at "The Hotel"

Officials with the U.S. Fish and Wildlife Service have confirmed that the animal spotted near the North Rim of the Grand Canyon is a gray wolf. As Arizona Public Radio’s Ryan Heinsius reports, it’s the first of its kind to be seen in the area in more than 70 years.
