Attitude is everything, the self-help books tell us, and in many ways they’re right. But in the West, altitude is everything.

On Saturday, we drove to the top of Mount Lemmon, 9,200 feet. From a start in the Sonoran Desert, all prickly pears and Saguaro cactus, we ended up in a cool pine forest, with a few dead tree trunks thrown in from the Aspen fire, which happened more than a decade ago.

Every 1,000 feet gained is like traveling 300 miles north, said the helpful sign at the top of the trail. By that reckoning, we were somewhere near Banff, Alberta, Canada.

Not bad for a morning’s drive.
