U.S. Highway 191 winds its way northwest through the rolling Gros Ventre wilderness, toward Jackson Hole and the sharp peaks of the Teton range. It’s punctuated by turnoffs to ranches with names like Bourbon Whiskey and Broken Arrow, but a 120-acre plot of land just below Mt. Anne serves a different purpose: it's a geological station for University of Michigan students called Camp Davis.
From above, the driveway toward Camp Davis looks like someone draped a ribbon across the land—it’s a full mile of packed dirt and gravel that crisscrosses the Hoback River with a 15-mile-per-hour speed limit. Groups of college students make the trip from Ann Arbor over a three-day span, strangers grouped in fives by a fleet of university minivans.
