Sun Dance
In 1963, John Trehero informed Yellowtail that his Medicine Fathers had instructed him to transfer the authority to run the Crow Sun Dance over to Yellowtail. For the next thirty years, until his death at age 90, Yellowtail served as Crow Sun Dance chief and helped perpetuate the Crow Sun Dance Religion. At the time of his death in November, 1993, Thomas Yellowtail was one of the most respected and revered Sun Dance chiefs and Medicine Men of the Crow tribe.
