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. 

Commissioned by Portland Center Stage at The Armory | World Premiere
