Sun Dance Trosper is responsible for holding the Eastern Shoshone Sun Dance each August on the Wind River Indian Reservation. This duty was passed down to Trosper through genealogical lines for seven generations, and also includes receiving and caring for a medicine bundle used in the ceremony. Trosper received the leadership of the Sun Dance through the line of his great-grandfather John Trehero (sometimes spelled Truhujo), who led the ceremony for much of the 20th century and authorized a branch of the Sun Dance on the Crow Reservation in 1941 to be led by Tom Yellowtail (Crow). Trehero died in 1986. According to a vision Trehero had experienced, in 1993 Tom Yellowtail conducted a blessing ceremony for James Trosper in order to pass authority for the Trehero Sun Dance for the Eastern Shoshone to Trosper. After attending a Crow Sun Dance led by Yellowtail in the Wolf Teeth (Chetish) Mountains of Montana in 1993, Trosper led his first Eastern Shoshone Sun Dance in 1994, with assistance of Yellowtail from outside the Sun Dance lodge. Yellowtail died the following month, having fulfilled his last promise to Trehero of passing along the Eastern Shoshone Sun Dance lineage. The two Trehero-descended Sun Dances among the Crow and the Eastern Shoshone continue to this day. Predecessor Eastern Shoshone Sun Dance leaders going back before Trehero included John McAdams, Andrew Bresil, Wuwuci and Bazil (Pa:si). Trosper is also a descendant of Yellow Hand (Ohamagwya), who founded the Sun Dance among the Shoshone.
