This session will explore the Story Map, “How Did Arizona Get its Shape?” which uses maps from the State of Arizona Research Library Special Maps Collection to tell a historical narrative of Arizona’s shifting geopolitical borders from 1679 to 1912. Maps are a unique resource that can be hard to “read,” but every map contains a story about that place. A sequence of maps, therefore, can tell a more comprehensive story about how a particular landscape changed over time. Story Maps connect the reader to a simple interface where they can learn the histories contained in the maps.
