“On the day that followed they crossed a lake of gypsum so fine the ponies left no track upon it. The riders wore masks of boneblack smeared about their eyes and some had blacked the eyes of their horses. The sun reflected off the pan burned the undersides of their faces and shadow of horse and rider alike were painted upon the fine white powder in purest indigo.”

—Cormac McCarthy, Blood Meridian, 1985.
