Lonesome Dove, Volume 1 by Larry McMurtry

JULY RODE FOR DAYS without seeing any person, or, for that matter, many signs of life except the hawks and buzzards circling in the blue prairie sky. Once he saw a wolf loping along a ridge, and at night he heard coyotes, but the only game he saw were jackrabbits, and it was mostly rabbit he ate.

He kept going north, reminding himself that it was a long way to any towns; but soon the unvarying emptiness of the country began to disturb him, and he was already disturbed enough by the deaths of the three people buried on the Canadian. He thought of them more or less all day. Waking in the gray dawn, he would have Roscoe's face in his mind; when he dreamed, it was of Roscoe and Joe and the young girl. Several times he cried at the thought of the finality of it. He had a longing to get them back in places they belonged: Fort Smith, in the case of Roscoe and Joe. He didn't know where the girl had belonged, though it wasn't in a grave on the Canadian.
