but which is it? Does it happen every 10 years, or is it "once in a lifetime"?

You know, birds, wolves, grasshoppers... Don't be so human-centric!

in Plain Awful (which is the name of the place) even the people are square and blocky-looking ... the story begins with the discovery of a square egg.

Calling Captain Sisko...

I need to get caught up on Netflix...

And as usual, fabulous character development!

And the ducks beat them to it without a starship. Talk about embarrassing.

Even from tens of thousands of feet up, it's damned impressive.

It's very hard to get a sense of the Grand Canyon from the ground. Although what's really considered the "Grand Canyon" is just the northern section, it actually stretches from Lake Powell to Lake Mead.

The canyons in south-eastern Utah were more impressive, both because of their more trippy-looking nature, and that they were smaller as easier to identify as canyons.

especially at 9:34 to 9:36 there appears to be an impact crater and at the upper left of it is the number "10" written in the earth. What is that about?

Flying high over the Grand Canyon I believe, gives you a better perspective because you can see the curvature of the earth and the canyon gives the impression that the earth is actually coming apart especially when the sun is low.

But at this point in the video I'm flying east of the Horseshoe Bend area along hwy 89, so you might be able to find something on Google Earth.

I have hiked down into the canyon at several places, hiked across the canyon, and taken the river thru the canyon. I have never seen anything like this. WOW The Grand Canyon is a special place. Wonder what it was like to be down at the ranch for this. Zowie.

I have weird job. I'm trained for both desert survival and Snow-cat operation, with an occasional helicopter flight to The Ranch.

ENOUGH with the Redi-Whip already!

The pictures don't do it justice.

...lost in a fog!

Thanks

Thanks for posting this!

Canyonlands when the same thing happened. The valley below was filled with fog, and it was rising. A mountain with a long, sheer cliff facing me was holding the fog back, but the fog was spilling over the top of the cliff and dropped down like a slow motion waterfall. It was really cool.

In camp in the morning it was overcast with a very low cloud ceiling. We starting hiking and soon entered the cloud bank. After a while (an hour? I don't remember) we exited the cloud bank and kept hiking up. Soon we had a clear view of the layers of "cotton" down in the valleys below us with our mountain and several around us poking through. And similar to what you saw, the fog was spilling up and around the sides of the mountains that were poking through. It was quite a sight that I will never forget.

You've seen something you'll never forget.

It was the key to the Donora disaster of 1948:

http://en.wikipedia.org/wiki/1948_Donora_smog

From October 27 till October 31, 1948 (when a rain ended the inversion) 20 people died do to the inversion.

Donora is a small steel mill town on a curve of the Monongahela River. Smogs have been common in this bowl between the hills; but, on the occasion in question, the atmospheric conditions were such as to make the accumulation of smoke and fog unusually severe and persistent. It began on Wednesday, and by Saturday the first death occurred. Before the atmosphere became clear again, 43 per cent of the 13,839 persons in the area were affected by an irritation of the respiratory tract, the predominant single symptom being cough. Fifteen per cent were mildly affected, 17 per cent moderately and 10 per cent severely. Over 60 per cent of persons 65 years of age and older reported some affection, almost half being in the severely affected group. Although onset in some cases was as early as the first day of severe smog, 40 per cent occurred on day Number 2. By the end of day Number 3, 17 persons had died; 3 more died shortly thereafter bringing total deaths to 20..
