Brokeback Mountain
Fiction by Annie Proulx, from 1997: “They never talked about the sex, let it happen, at first only in the tent at night, then in the full daylight.”
On two cowboys beginning their ascent: "Ennis and Jack, the dogs, the horses and mules, a thousand ewes and their lambs flowed up the trail like dirty water through the timber and out above the tree line into the great flowery meadows and the coursing, endless wind."
