Sunday, April 19, 3:00–5:00 pm, at St. Mary Magdalene Episcopal Church, 4775 Cambridge St., Boulder, CO 80301. Have you wondered about Colorado's Indigenous history? Are you aware of the Doctrine of Discovery? Would you like to know more about the 1864 Sand Creek Massacre? Why are there no Indian reservations on the eastern plains of Colorado? Join us for a talk with Rick Williams, an enrolled member of the Oglala Lakota Tribe and leader of the People of the Sacred Land, a CO nonprofit dedicated to uncovering the truth about Native-land dispossession and supporting Indigenous cultural preservation.
