A raging thunder and lightning storm builds to the far west late in the evening. Then, well after dark, it comes on inexorably, way driven through constant growing grumbling rumble, and a bright sky from Light deep within low dense cloud. Some long exposures, hand-held, in almost complete darkness (though this was rare in the instance of the almost constant lightning!) With a tinged glow from the east — Grand Junction’s quite shameful Light pollution. I wish they could follow the lead of Flagstaff’s dark skies initiative.
