The water table used to be much higher. Pete Kitchen's Ranch was photo graphed and showed pine trees around it. Now it is all scrub desert. The Iron Door mine, I thought was supposed to be a Jesuit mine, not Spanish. With the converted Indians working the mine, "For the Glory of God", as were most if not all of the Jesuit mines. Maybe I am wrong about that, would love to hear differently as I can't see the priest working in the mines when they could use local labor instead. Sheep were not that common back then. The Basques came later. I'm thinking of time frame 1560's(?) or when Kino came through, to 1767. Pima Indians were "Friendly" because they wanted allies against the Apaches and the Papagos, that they were at war with because of raids on them(1880's). Florence where I went to HS was only 9 miles from the Pima Reservation, now part of the Salt River Reservation. Your still talking 55-60 miles from there to the Catalinas, for transporting food for mining there. What would they trade them for the food? Gold or Silver? I don't think so. Those went back to Mexico for shipment to Spain (Jesuit).
