Tribal authorities have reportedly reached an agreement to purchase a sacred piece of land known as Pe' Sla in the Black Hills.
Lakota leaders announced the tribes will purchase nearly 2,000 acres of the land.
After several weeks of intense fundraising, the nine tribes raised enough to make a deal with the current owners of Pe' Sla. Details of the arrangement are still being negotiated.
A rally is scheduled for five p.m. Wednesday at the Memorial Park band shell in Rapid City to celebrate the news.
