We keeps our speed to twenty miles per hour or so as we drive up Dun Glen Canyon Road, a dirt road barely two cars wide that wends some nine miles northeast from where we left the 80. A huge slash of yellow dust boils in our wake, coating the entire rear windshield and rendering the rearview mirror useless. I glance down at the directions on my phone. Dun Glen—what’s left of it, anyway—is three miles, twelve minutes away.
