I noticed the clouds. But they seem more white than the "puff", and the clouds seem to be building, while this comes and goes. Also, the clouds seem to be forming over mountain ridges. The "puff" is at the northern edge of a dry lake bed.

Here's the animated GIF. The real animation is more convincing, since data is lost in the GIF conversion. The bad pixel I called a "guide pixel" did not make it through the GIF process. The top image is a still image of the area. I put a red dot on the "puff". The bottom image is 4 frames of animation.




This is what the area looks like upclose on Google Earth. The puff is just north of the edge of this lake bed:
