SHERIDAN — A lecture planned for Sunday at The Brinton Museum will explore Cheyenne Indian spirituality.

The event — organized by The Brinton Museum in partnership with the Congregational UCC Churches of Sheridan and Buffalo — will begin at 2 p.m. and will feature Linwood Tallbull.

A resident of Busby, Montana, Tallbull is a member of a venerated, traditionalist Northern Cheyenne family and a leader of the Dog Soldier Society, one of four Cheyenne sacred warrior societies. An ethnobotanist and teacher at Chief Dull Knife College in Lame Deer, Montana, he is a member of The Brinton Museum’s American Indian Advisory Council, established in 2014.

Admission for the event is free, and light refreshments will follow the lecture.

The Brinton Museum is located at 239 Brinton Road in Big Horn.
