One of Central Oregon’s most significant cultural gatherings is just weeks away. The Pi-Ume-Sha Treaty Days celebration returns to Warm Springs on June 26–28, 2026, drawing visitors from across the region for a three-day commemoration of the Warm Springs Treaty of 1855 and a celebration of tribal culture, tradition, and community.

Parade Theme: “Honoring the Horses”

This year’s traditional parade carries a special theme: “Honoring the Horses.” Organizers with the Confederated Tribes of Warm Springs are calling on community members to bring out their horses in all forms — traditional, ranch, rodeo, family, or therapy — to celebrate the deep bond between the people and these animals.

In a statement, organizers wrote that horses have always been a central part of the people’s way of life, culture, healing, and identity — and that this year’s theme is about ensuring that bond is “seen, celebrated, and remembered in a good way.”

What Organizers Are Looking For

Participants are invited to showcase:

  • Traditional regalia and horse masks
  • Sacred paint designs
  • Cowboy and ranch-style riders
  • Youth riders representing the next generation

The parade will also feature its traditional lineup of walkers and floats, with divisions for adults, teens, and youth. Strong community sponsorship this year means organizers are excited to show extra appreciation to participants.

Parade Registration

Registration for riders and float drivers opens Friday, June 26 at 3 p.m. at the powwow grounds and closes on the morning of the parade at 10:00 a.m. sharp. All participants must be registered to join the procession.

Leading the procession as 2026 Grand Marshals will be representatives from the Traditional Horses community and the Rodeo Committee.

About Pi-Ume-Sha Treaty Days

Pi-Ume-Sha — meaning “to give back” in the Sahaptin language — is an annual commemoration of the Warm Springs Treaty of 1855, in which the Warm Springs, Wasco, and Paiute peoples ceded millions of acres of land to the United States while retaining hunting, fishing, and gathering rights. The celebration includes a powwow, rodeo, stick game tournament, traditional parade, and other cultural events. The public is welcome to attend.
