Autumn color across the United States depends as much on elevation as latitude, with displays starting in high tundra as early as August before descending into river valleys through November. Outside outlines typical peak windows across a dozen major national parks, from the subalpine meadows of Mount Rainier to the hardwood ridges of the Great Smoky Mountains. It is a clear, practical primer for anyone planning a seasonal road trip or weekend hike.
