Isleta just means little island, but the place is like a knife. The Tewa word for this open place of sun and wind is Shiewhibak. At this pueblo on the Rio Grande, on a spit of ancient lava, light bleaches the fields to dry colors. Albuquerque is shouldering in from the north. The land is both bucolic and fierce. Rabbits and cattle love this place, and, nearby, there is a casino that supports it.
