In February 2021, artist Moira Villiard debuted her installation, Madweyaashkaa: Waves Can Be Heard as the fourth installment of the Illuminate the Lock series at the closed Upper St. Anthony Lock and Dam in Minneapolis, Minnesota. On three chilly February evenings, 2,500 people walked through the snow on top of Upper St. Anthony Lock and Dam to watch what Villiard calls an “animated video collage” projected on the 49-by-400-foot concrete walls of the no-longer-functioning lock.
