2011 Land Report 100: Irwin Heirs

No. 46 Irwin Heirs

210,000 acres

John Irwin II purchased the historic O RO Ranch in the early 1970s, and today the land is owned by his heirs. The O RO is the only ranch in Northern Arizona with a Spanish land grant in its chain of title. Its horses can also be traced back to Mexico’s Cananea Cattle Company.
