Lesson 4: Maps of the Missouri River Valley

In this lesson, students will compare two maps documenting the confluence of the Missouri and Yellowstone rivers to discover how two different groups of people can understand the same location in varying ways. One map was created by a Mandan Indian documenting the human interaction with the region, while the second map was prepared for the federal Bureau of Topographical Engineers, and it is primarily concerned with geology. Finally, students will connect these sources to the recent Standing Rock movement to illustrate connections between historical maps and modern social justice issues.
