The Black Hills Unity Concert, sponsored by Peter Yarrow of Peter Paul and Mary, was held in 2014, 2015, 2016, and 2017 in the Black Hills. Although it was not officially connected to the S.U.T. Gatherings, it was a related event and many S.U.T. people participated. The purpose of the Black Hills Unity Concert was to raise awareness of the need to restore guardianship of the Black Hills to the Lakota/Nakota/Dakota people.
As of 2019 there have been many Spiritual Unity Gatherings held worldwide, including two on the Peaceweavers’ land in New York State, two in Siberia, several in Alaska, five in New Mexico, 14 in the Black Hills of South Dakota, and 21 in Australia.
