Utah’s Snow-Covered Bryce Canyon

Utah’s Bryce Canyon is not the deepest canyon in the United States; its largest “amphitheater” of naturally eroded rock drops 240 meters. Arizona’s Grand Canyon, for comparison, measures more than 1,800 meters deep in places. But photographers who visit Bryce Canyon National Park typically aren’t looking for dizzying heights and depth; they’re often trying to capture images of the delicate spires called “hoodoos” that rise from the canyon.
