Organizers are expecting more than 100 people from the Ute Mountain Ute, Navajo and Shoshone/Cree tribes to participate in the event, which marks the beginning of spring, said Afrem Wall, a member of the Ute Mountain Ute tribe.
Although American Indian traditions typically don't observe Judeo-Christian holidays, many tribes commemorate the changing of the seasons.
"Easter comes at the beginning of spring," Wall said. "Other cultures celebrate Easter as the time when Jesus rose from the dead. In our culture, we celebrate when spring is coming."
