looks like it was selected and edited (desaturated), if you look along the tree lines where the sky meets the trees you can see its lighter close to the trees

It was a basic editing challenge so I hope not! :P
though the sky has a vague 'IR look' I'm sure it isn't because the trees look quite normal...it just looks like a heavily Burned sky using the burn tool in Photoshoppa..and actually it is quite a poor/sloppy job at burning to boot.

Well that was my first thought with the hazed edges and blowouts- also the top left sky is pretty much pure 'zero' black.
however I am trusting he did not edit that way so i am intrigued as to how I too can obtain nice dark skies in basic editing! As I loike them a lot :D
If you use a red filter on the lens, it allows red light through (filtering out green and blue - you would notice trees go dark too).
An infra-red filter allows infra-red light through, which trees reflect very well, so in a pic like your example the trees would have come out very light.
Likewise, if you use a blue filter it will filter out red i.e. make red in the image appear as black or near black.
This works on black and white film - I've never tried it on digital in colour and then converting to gray, so the effect might be different.
However, looking at that pic again, see the edge of the trees have a "glow" about them, especially in the distance? This to me shows that quite a bit of burning has been applied to the sky area, but not quite down to the tree line.
I'd normally achieve this through multiple layers of dodging & burning and use of the Overlay, Linear Light, Linear Burn adjustment layers. You can tell where it's been given this selective treatment through the halos around all the land areas.

I thought they only work (colored filters) with B&W film
In Photoshop, you can do a pretty good job on this with the Calculations dialog from the Image menu. Just select the red channel in one or both of the "source" dropdown menus and your sky should turn satisfyingly dark. I think that's how I did my Palomar shot:
I definitely agree with stark. Looking at the image on my graphics workstation monitor it looks blatantly obvious that someone got a tad too heavy handed with the burn tool: there is just a lot of unnatural blotchiness between where they chose to use the tool and where they chose not to, not only at the horizon but all over the sky/clouds.

Try shooting with a polarizer, then converting using channel mixer with RGB respectively set at 100, 100, -100, and you should be close (and legal for Open Challenges). That's the easiest way I know.

That tends to bring huge noise and also darkens the floor when I do it.
Given that most people here don't care about getting it right in camera just plaster your shot with adjustment layers, dodge & burn (maybe even paste in another sky from a different shot) and - voila! - the perfect end result.

Make sure the blending is set to "multiply." I just tried it on a few other images with blue sky and while it doesn't get as dark as my Palomar image it does work. Maybe works best with a deep blue to begin with (polarizing filter)?
The Channel Mix, whilst working to some degree really adds lots of noise so is unsuitable for print (although burning likes to give noise too)
But it also blows out the opposite channels it seems -look at the colors of the bricks.
The burning method is great, you can be more precise with the tool and leave other parts of the images intact.
I would like to see burning added to basic editing, because people will just try to get around it via other methods which hinders their photography and also teaches bad photoshop practice.
