Sunrise, Grand Canyon National Park, Arizona

I’m continually surprised by how cold a desert like landscape can be in the early morning. The lack of any significant means to retain heat means a landscape like this can easily drop below freezing at night and skyrocket in temperature during the day. In this photo, the sun is just beginning to peak over the mountains, casting wonderfully golden light on the rocks across the canyon. The light bounces off the opposite cliff wall and helps to back light some of the rocks in a warm glow.
