Clouds form when warm, humid air rises into the cooler atmosphere, and all that water vapor condenses into tiny floating water droplets. But sometimes that process can be inverted, like when cold air trapped in the Grand Canyon causes it to fill with clouds as warm air passes over the massive gorge. And sometimes,…
An appeals court ruled Tuesday that a 20-year ban on new uranium mining along the Grand Canyon will remain.

December 11 was a weird day at the Grand Canyon.
This view may look like it shows the view from high above the clouds, but what you're seeing is actually the ground-level view of what it looks like to look over the Grand Canyon right now.
The hike down into the Grand Canyon is a rewarding one, full of gorgeous views. It's also, however, a treacherous hike with 250 of the people who attempt the route eventually needing rescue from the National Parks Service annually. Just what makes it so dangerous?
Developers want to put gondolas, hotels and shops in and around the Grand Canyon, in what the National Park Service has called the "most serious threat the park has faced in its 95-year history."
It's tempting, when one visits Grand Canyon National Park, to focus attention on the mammoth hole in the ground (both for safety and for gawking purposes). This timelapse, though, makes a pretty good argument in favor of looking up.
There are more than seven billion human beings living on Earth. That sounds like a lot until you imagine all of them sitting in a pile in the Grand Canyon.
In 1956 two planes collided over the Arizona desert, killing all 128 people on board and scattering the debris deep inside the Grand Canyon. This week, the National Park Service designated the crash site a National Historic Landmark—even though they don't actually want you to go visit it.

The ice sheet that covers Antarctica is ancient, hiding a whole landscape of mountains and valleys that once teemed with life. Using radar and satellite footage, scientists are studying this hidden world—and they just found a two-mile-deep canyon down there.
You're looking at the Grand Canyon completely flooded by clouds, "a once in a lifetime event," according to park ranger Erin Whittaker. It didn't only happen once, she says, but two times in only three days:
Over the weekend, rare atmospheric conditions gave rise to an even rarer scene: The Grand Canyon – that vast, gaping wonder of the natural world – filled to the brim with cold, dense, roiling fog. National Park officials have called the sight a "once in a lifetime" event. Looking at these photos, it's not hard to see…
Photographer Rolf Maeder recently traveled to the Grand Canyon in hopes of taking some pictures of the sunset, but an incoming lightning storm required a change of plans. This astonishing photo of multiple lightning bolts and brilliantly illuminated canyon sky is the result.
We've seen how New York City might appear were it suddenly transported to another planet, but what would, say, Manhattan look like if it were transplanted somewhere else right here on Earth – Death Valley, for instance, or the Grand Canyon? Well... it would look something like this.
Google strapped backpack-mounted cameras onto members of their team and sent them trekking through the Grand Canyon. The end result? Google Street View for Arizona's great gorge, though a more accurate description would probably be "Trail View"; according to the official Google Blog, the company's newly released…
