Tucson
Two large masses, one ring-shaped (the Signet or Irwin-Ainsa Iron) of 688kg and the other (the Carleton Iron) of 287kg known for centuries, had been transported to Tucson from the Puerta de los Muchacos, a pass 20-30 miles S of that town and were used as anvils; first mentioned by J.F.Velasco in 1850, M.H.Hey, Cat.
