This is one of several occurrences over my home i Colorado, west of Colorado Springs.

Pretty much the view everyday for 20 years here in Norcal
there are multiple reasons, a big one is the metal powder
in the trees make them burn white hot. they stopped the
Cal Fire fighters a few years back from talking about it as
it was so noticable to them. they spray to keep the rain
away to aid in our many fires. also it poisons the soil to
affect growing and kill forrests for more fire

Wow! How many did you count that day? I had 15 in one day in Fl-Ga line
