While at Woomera, and in fact as we continued to move north, I was fascinated by the sky. The photo below is at Woomera, while the photo at the top of the blog is from later that same day, in the small settlement of Glendambo. The clouds, like brush strokes from a nearly dry paint brush, stood out in strong contrast to the blue sky.
I later learned that this type of cloud is known as a mare’s tail, or, more scientifically, Cirrus uncinus. In addition to not knowing their name when I first saw them, I also did not know (but would soon learn) that they presaged rain.
But during that day on the road, I was not thinking of what the clouds meant, just that they were remarkably lovely.

Doncha love clouds, and their classification? Great shot.
Thanks. And yes, I do love clouds. I have huge notebooks filled with sheets and sheets of slides of skies from everywhere I’ve traveled, as well as thousands of slides from at home. If you keep looking up, you’ll be dazzled.
