Driving behind one of the haul trucks at Morenci. Morenci is a HUGE copper mine. It's one of those "can't see the forest for the trees" kind of places. It's so big one almost doesn't realize they're IN the mine. Makes Chino look small! Was a good day, though. (Got to work with Geo ALL day! How lucky is that? Getting to geologize with my spouse - and we work really well together.)
