Shortly after they left the ranch they passed an enormous black stone. On the stone Lalo thought he saw a Gila monster, motionless, staring into the endless west. They say that stone is really a meteorite, said Pedro Negrete. In a gully, farther to the north, the Río Paredes curved, and from the road the tops of trees were visible like a green-black carpet with a cloud of dust hanging over them where Pedro Rengifo’s cattle came to drink each afternoon. But if it was a meteorite, said Pedro Negrete, it would’ve left a crater, and where’s the crater?
