A quick review on my iPhone app the night before showed sunrise at 6:20 a.m. Perfect, I thought, just enough time to catch the dawn without feeling like I’d need to set an alarm that sounds like a foghorn. We planned a 15-minute drive into the park to snag parking near Sunset Point, Thors Hammer, and Inspiration Point. Parking is limited, which means it’s basically a race against the sunrise or at least a race against the early risers a.k.a. professional photographers.
