How the maps are made
The Story Map uses the Story Map Journal, and embeds two Story Map Series and the Time Aware configurable app.
The interactive map shown above uses the sharing preview of the map in the Minimalist configurable app. For more information on this "quick share" technique, see Quickly share your map using an app.
