I used to think that Yellowstone was more bizarre than beautiful. Not anymore. America’s first national park offers a landscape of extremes: spewing geysers, bubbling mud pots, hot springs, cold rivers, violent waterfalls, languid lakes, lush valleys, a rocky canyon and peaks just high enough to force a flatlander’s breath. The sky changes constantly. Blue above. Gray over there. Mist on the horizon. A rainbow over my shoulder. There’s wildlife everywhere. And endless photographic possibilities. I could spend a lifetime here. I had three days. And my handy smartphone camera. Travel light. Rise early. Stay out late. Look everywhere. In a general store, I found souvenirs. And a T-shirt promoting Yellowstone as the “oldest & best.” I bought it.

The Yellowstone River runs through the Grand Canyon of the Yellowstone.

A bison heads for a meal after lounging at the edge of Mud Caldron. Because of hydrogen sulfide, the area smells similar to rotten eggs.

A yellow stream runs through Biscuit Basin.
