Illuminations in the Subway at Zion NP

Happy Thursday Everybody!  Here’s another one from one of my recent excursions to the Southwest.  Subway_Keyhole_Glow_Jeff_McGraw_PhotographyWarm evening light filling the keyhole at the Subway in Zion National Park. At the base of the slot a cool stream fills a set of turquoise pools. The cavern rocks form a semi circular tube with a thin section splitting open the roof. It’s an interesting effect that allows cool ambient light to illuminate the passageway while a simultaneous warm glow radiates into the cave opening (appearing to the right). What a great area to get out and explore!
