“Under the hooves of the horses the alabaster sand shaped itself in whorls strangely symmetric like iron filings in a field and these shapes flared and drew back again, resonating upon that harmonic ground and then turning to swirl away over the playa. As if the very sediment of things contained yet some residue of sentience. As if in the transit of those riders were a thing so profoundly terrible as to register even to the uttermost granulation of reality.”

—Cormac McCarthy, Blood Meridian, 1985.
