On Tuesday, I wrote about the Zion Narrows River Trail which goes for about a mile upstream along the Virgin River. At the end of that trail, you must hike in the river to go further upstream. The canyon narrows even more. In January, you need to wear neoprene boots and rubberized pants to stay warm. I’d hoped to post more images of the hike, but Friday got away from me, and I did want to share one image. Due to its narrowness, sunlight doesn’t get into the canyon walls until near noon. Then for a short while the walls glow in the canyon light.
