There are strange cloud formations and there are strange cloud formations.
And then, there are these.
Look carefully from the first photo to the last.
Photo one thorough four are all of the same "spike" formation. By the time you get to the fifth photo, the spike is well on it's way to dissipating, with another forming to its left.

Ultimately, in the final photo, this second spike has taken on a surreal likeness to an insignia all Star Trek fans out there will recognize immediately: That of the Klingon Empire!
Mayhap a sign Klingons really do exist?
