Ted Burrowes, a friend of Alexia Smith (Member 49,439), noticed these curvilinear clouds over Lexington, Virginia, US. He was near where the Blue Ridge Mountains and the Alleghenies meet and wondered if the local topography had shaped them.

We think they’re too high to have been shaped by the nearby mountains since this is the high ice-crystal layer cloud Cirrostratus that’s in the form known as fibratus. That is when the winds have stretched it into long, fine parallel filaments, like hair combed neatly across the sky. The tidy hairdo is only marred by the Cirrocumulus in the middle, which looks like a bad toupée trying to cover a bald patch.
