Sundance Ceremonial Structure

This could be the structure built for the Sundance, a Indian ceremony that is considered very spiritual and sacred. The definition from Wikipedia describes the Sundance as follows: At most ceremonies, family members and friends come to pray and support the dancers. People camp out at the site for many days. In preparation for the Sundance, wood and medicines are gathered in the traditional manner, the site is set up, offerings are made, elders consulted, trees are chosen and cut, and feast food is prepared. Much time and energy by the entire community is needed for the Sundance to work. Communities plan and organize for at least a year to prepare for the ceremony. Usually there is one leader or small group of leaders in charge of the ceremony, but many elders help out and advise. The Sundance was the most spectacular and important religious ceremony of the Plains Indians of the 19th century North America, ordinarly held by each tribe once a year usually at the time of the Summer Solstice.
