As autumn slowly marches southward, the color usually peaks around the end of October in the desert canyons.  This is trick-or-treat for photographers, as sometimes the winds kick up with passing storm fronts.  Most years, however, the transition is subtle, and it feels like we can’t shake off summer.  That’s when the maples are allowed to reach their deepest hues in the deepest canyons.
