"Pekin" Guerrero, in his 70's, still rides on a regular basis. Several times a year he and his son herd cattle down from their ranch in the mountains and make the three-day trip by horse to corrals where the animals can be weighed and loaded. Pekin carries his own equipment, getting up at dawn to saddle his riding and pack horse for a full day ahead. The Paine Massif, bathed in pink light, rises in the distance. The future of cattle ranching in Southern Chile is uncertain as each year more ranchers sell or divide their property to outside investors and others begin to dedicate more time to tourism than to livestock.
