PINE RIDGE, S.D. (AP) — A school on the Pine Ridge Indian Reservation is opening an art installation project that examines a congressional apology to Native Americans.

The Red Cloud Indian School’s Heritage Center will feature the project by Oglala Lakota artist Layli Long Soldier beginning Tuesday. The interactive piece looks at the 2009 apology issued to Native Americans from Congress. The resolution apologizes to Native Americans for “ill-conceived policies” and acts of violence.

People will be invited to write or draw their own response to the apology as part of the installation piece. It will remain at The Heritage Center through December.
