Haines Junction, Yukon.

Although this valley was not on our route of flight, its appearance is typical of much of the flying we did through Alaska and Western Canada.  Good forward visibility, valleys wide enough to safely turn 180 degrees, and endless flat sandbars made it "reasonably safe" throughout the trip, and the feeling that most of Alaska was connected by these "aviators tunnels" became second nature.  Partly to conserve fuel and engine wear, but mostly just because we were enjoying the flying so much, we flew most of the trip under very low cruise settings.  The other advantage of flying slowly is that narrows the turning radius, effectively "widening the valley".
