Hot Spot As I circle the half-mile wide maw of Cerro Colorado, one of at least 10 craters and 400 cinder cones that pock Mexico's Pinacate volcanic field, I think of Jesuit missionary Euse bio Kino's treks across this tortured land. When Kino's party crossed the Pinacate in 1701, a member wrote of find ing a "hole of such depth that it caused ter ror and fear." It wasn't Cerro Colorado; its floor is only 13 feet below the surrounding desert. Morning shadows appear to deepen it.
