Love those matching grins! That DOES look like "chukar country"!
Once I was hunting dogless in a place like that and took a shot and remember thinking "Oh crap, I HIT one!" (they were going downhill fast when I shot). I also remember being the bottom dog in one of those big V-shaped canyons and taking an incomer flushed by one of the guys up higher. The dead bird almost took my head off! Chukars can RUN uphill darn fast and they can FLY downhill near supersonic.
