Crossing Mnisose (“minne-show-she”) tells the story of one of America's first feminists, Sacajawea, and draws a line from a completely original view of Lewis and Clark to the present day, as descendants of the Dakota and Lakota Nations continue their fight for the Mnisose (or what Europeans named the “Missouri River”) and the lands that contain the burials of their ancestors. From celebrated playwright, activist, and attorney Mary Kathryn Nagle (Cherokee Nation), whose Manahatta captivated audiences at Oregon Shakespeare Festival.

An Interview with Mary Kathryn Nagle

The playwright discusses deconstructing the mythology of Lewis and Clark, learning the truth about Sacajawea, and how her experiences at the Standing Rock protests and as a lawyer fighting for Indigenous rights informed the writing of Crossing Mnisose.
