There are several ways not to walk in the prairie, and one of them is with your eye on a far goal, because you then begin to believe you’re not closing the distance any more than you would with a mirage. My woodland sense of scale and time didn’t fit this country, and I started wondering whether I could reach the summit before dark. On the prairie, distance and the miles of air turn movement to stasis and openness to a wall, a thing as difficult to penetrate as dense forest. I was hiking in a chamber of absences where the near was the same as the far, and it seemed every time I raised a step the earth rotated under me so that my foot fell just where it had lifted from. Limits and markers make travel possible for people: circumscribe our lines of sight and we can really get somewhere.
