Title: What causes a Cloud formation like this?

I'm sure it is something "interesting" from a weather perspective.

These photos are looking West-Southwest if that makes any difference.

Cirrocumulus stratiformis[5]
Sheets or relatively flat patches of cirrocumulus.

http://en.wikipedia.org/wiki/File:Cirrocumulus_to_Altocumulus.JPG

Clouds of the genus cirrocumulus form when moist air at a high altitude reaches saturation, creating ice crystals. Limited convective instability at the cloud level gives the cloud a rolled or rippled appearance. Despite the lack of a 'strato' prefix, cirrocumulus is physically more closely related to stratocumulus than the more freely convective cumulus genus.

I was gonna say an alligator rolling over in the sky, but I guess your answer works too.

I was kind of expecting someone to say either "George Bush" or "Global Warming", but Al's answer impressed the heck out of me!

I just noticed but the OP(the site's resident ubergeek) offset the images to stitch them together. Nicely done. :clap:

I do what I can.
