From the first time I glimpsed Devils Tower 7 years ago I’ve been dreaming of this picture. Countless visits to this iconic monolith were all badly timed for catching the aurora. But since then I’ve explored almost every acre of the park to figure out exactly where to go when the moment was right. That right moment happened on April 23rd. Two days earlier the sun hurled a massive explosion directly towards Earth at more than a million mph. When it arrived it caused the strongest geomagnetic storm since 2005. My widest lens, which covers a field of view of 115°, was not nearly wide enough. The entire sky pulsed in green waves like lightning. The raw intensity was humbling. I could see the ground by the light of the aurora alone. Since the ice recently melted, I headed for the Belle Fourche River. The water level on the shallow waterway was high enough to provide a perfect reflection. Because it's still the off-season, the park was much quieter with less stray light compared to the summer. I don’t know how many hours of sleep I’ve lost through the years chasing this shot. But it all feels worth it now.
