Reading the atlas

History pins sit on today's landscape. Dates describe the story associated with a place. Guided journeys connect related places; their lines are reading paths, not surveyed historical routes.

Relief emphasizes height to make the terrain easier to read. Set it to for the unexaggerated view. Use right-drag or two fingers to tilt and turn the map.
