While we're seeing Bryce Canyon under the summer sun, it's the cold that's responsible for this national park's unique red-rock pinnacles, or hoodoos. Set high above sea level, the canyon sees frequent shifts between above- and below-freezing temperatures. Hoodoos formed as water seeped into massive stone plateaus, then froze and expanded to break away chunks of rock. Repeated day after day for eons, this process has left slim sections of sediment standing throughout Bryce Canyon—now the largest concentration of hoodoos in the world.
