bri,
Of course, it's Cowley. If anyone would get it, I suspected it would be you.
The Rocky Mountain lee-waves at Cowley are particularly strong, since the 15 nm long Livingstone Range has 4000' of relief on the downwind side:
The picture is from
Cowley; Canada's Diamond mine. For anyone interested in wave-flying, this site is worth a look.

Cowley airfield was built in 1938 as an emergency landing ground for TCA's Electras. A weather station was built there too, hence the YY designation. Today it is the only YY airfield that is grass and does not have any commercial traffic.
I spent many idyllic days there over the years, towing , instructing and wave-flying, including a Diamond altitude. Chief Tow Pilot's briefing one day "The rotor is not rough unless the tow-plane gets rolled inverted."
cuefaye,
Why do you feel it is pointless? If it really is, from your point of view, then don't click on the link.
