The Vulture was the richest gold mine in Arizona, and its camp hanged eighteen men from the ironwood by the assay office, most for high-grading ore. The preserved buildings run tours now, and the stories run with them. Henry Wickenburg found the lode in 1863; the district records around it are real.
