LUVERNE, Minn. – Jim Brandenburg is turning himself this way and that, peering beneath a ledge of purplish Sioux quartzite. Barely waist-high, the outcropping still is prominent on the grassy plain of Touch the Sky Prairie in southwestern Minnesota.
He’s angling for a better view of a small piece of quartzite wedged beneath, as if someone tried to prop up the larger rock. He’s seen such wedges before in his travels to Norway, to Russia. Yet how? By whom? And why?
Brandenburg has ranged this territory all his life — his childhood farm is within sight — and says he often imagines himself in the past, maybe as an Indian on some rock, striking flakes from flint for an arrowhead, flakes that he seeks whenever he sees a pile of dirt heaved by a badger that’s unintentionally brought history to the surface.
Finally, with a decent view of the wedge, he’s ready to take a photo for anthropologist friends who might shed some light on this mystery.
Brandenburg reaches for his iPhone. Just for a moment, he catches himself.
“This is what it’s come to,” he says with a chagrined look, trying to laugh it off. “Even I find myself first reaching for my phone.”
You’ve seen Jim Brandenburg’s photos, whether you know it or not.
The National Geographic has published them for more than 30 years. Four of his images are among the 40 most important nature photographs of all time, as chosen by International League of Conservation Photographers — more than from anyone else, even Ansel Adams.
