Dear Biju, When a "u" word is pronounced as though it begins with a "y" (yoo nique), it's treated more like the consonant sound of the y. So, a university, an umbrella, a usual day, an unusual day. 

Your query, however, should've been- 

"thanks to a unique weather phenomenon" .  " a unique"? Is this form of grammar used to validate the verbal delivery of an expression, or is that a mistake ?

No confusion, great combination. ;)

We were there to witness this phenomenon, which made a different view from all the photos of Grand Canyon we have always seen. Although unfortunately for me, I never got the see the "real" canyon (minus the huge cloud pool) while I was there.. It was slightly disappointing for someone like me, who travelled so far just to see the majestic canyon!

We were to take a helicopter into the canyon that day but it was cancelled.  Maverick Helicopters refunded us our money  but it was very disappointing. The canyon looked like a river but it was fog not water.

Impressive views of the Grand Canyon as always, but temperature inversions are far more common than this article suggests. Looking down on fog or cloud tops is not unusual in areas of valleys and high ground such as mountain ranges.

It's also the same meteorological condition that causes smog to hang over large cities like LA.

I was there, and it really was breathtaking! We hiked into the canyon, and under the clouds the air was warm and clear.

Hi all,


I live a couple of 100 metres from Govetts Leap Lookout at Blackheath west of Sydney in the Blue Mnts.

We get this inversion layer phenomenon all the time over Govetts lookout into the Grose Valley.

What makes it even more awesome is when the fog lifts to your nose and you can only see a blanket of fog around your ears.

And then the fog  can rise and fall several times with atmospheric pressure fluctuations and you get this surreal feeling of being caressed by the fog.


Come on down to Oz. Check it out.

Wow ... thanks for sharing these with us. It's such a different view of the Grand Canyon. 

For a while i lived up the hill a bit from Lick Creek, MO. Many mornings i looked out at the river of mist flowing down the valley. And now to see the cloud covered Grand Canyon...... thank you

Real fascinating. I wish I was there to see this unique mother nature' s drama.

This is also well described phenomenon. 

Thank you National Geographic

@Swati Gupta  Even though this is pretty, I do feel bad for the people that only had that day to see the canyon.  We were there over the summer and only had one day scheduled to see the canyon.  Sorry - I hope you get to see it without the cloud cover.
