Hello, it is Hitoritabi Mile.
The European line goes by way of Anchorage in those days as I was not able to yet fly over Siberia. It was a night takeoff, but I came back halfway in the afternoon of the day before, and the wilderness of Alaska spread out under eyes. The Yukon which winds. The river with nature on did that I meandered in one of eyes.
(I photograph it from the plane of DC10 in Yukon February, 1976 when I saw it from the sky)
