Remnants of a Firey Space Rock?

Strangely beautiful dawn "clouds"

Just before dawn, curious clouds appeared on the horizon. They were strangely bright relative to the rest of the sky, and as the dawn progressed, other similar clouds became visible. Were they “contrails” from aircraft? A meteor’s smoke trail?

Later in the day, Anthony Arrigo, Utah Skies C0-Founder and President/CEO of Starry Night Lights brought to my attention the news of a giant fireball seen over the western US earlier in the morning, lending much credence to the theory that these “contrail clouds” were the smokey remnants of not just a bolide, but that of a small asteroid!
