What is Salt Draw?

The main setting of "Half Broke Horses" by Jeannette Walls is located in western Texas. The Casey family lived on High Lonesome, a ranch in the heart of a difficult land. Lily describes the property: "When you looked out across the land, most everything you could see - the horizon, the river, the fence lines, the gullies, the scrub cedar - was spread out and flat, and the people, cattle, horses, lizards, and water all moved slowly, conserving themselves." (Part 1, p. 6).
