I figured, but it was just for fun, so I just left it a 6-7,000 ft. sky.
You probably don't get that kind of clouds up there either, but they
were cute. :-)

And a very useful illustration it is, too. It graphically showes both
the unnatural sky you get with a polarizer at high altitude and the
unnatural overall blue cast at altitude without a fliter that I was
talking about. I have nowhere near as good an example as you have provided.
Of course, correction is simple with this subject. If the Peruvian AF
heli were a strong blue, and you took a shot of it on the snowfield, it
would be a different story. Correction for the overall blue cast from UV
would wash out the heli.
Thanks,
