The glow is from the sun hitting the rocks. These pics are from a drive I took today. Were taken with an iphone 12 pro max. No filters, no editing. Just a straight picture. This is up by Zion Lodge which is only open to cars from December to around February. Reason it's open because there's not a lot of tourists when it's that cold and during the holidays. I went yesterday (Saturday) and today. I try and go almost every weekend. Been there so much that I know the cops in Springdale and a few of the Park Rangers.
