Sunset illuminates Horseshoe Bend in Arizona. Part of the Glen Canyon National Recreation Area, Horseshoe Bend is a stunning natural wonder created by the meandering Colorado River. Every time you visit, you’re guaranteed to see something new. The colors of the rocks change throughout the day as the shadows move in and out of the canyons. Photo by Sylvia Zarco.
