On the days last week when the sky was expansively blue and mostly empty of clouds I did notice one cloud that seemed to stretch in a narrow band across the sky.
New Zealand is also known as Aotearoa and one translation that has been popular in my lifetime is “Land of the Long White Cloud”. This certainly was the case at times last week.

I photographed one like that above our house one day. It definitely wasn’t a jet-trail
This wasn’t a jet trail either and appeared over three days when the rest of the sky was utterly clear. It seemed to stretch a long, long way. Interesting you have recorded a similar image.
I’ll see if I can hunt it out. I did research it at the time, and it was something to do with a particular front…
I love long clouds like this….almost as though they invite us to go for a walk along them….
This was a fascinating cloud in such a clear sky. I love your idea of walking along them.
