Tipi
A tepee ( ), also spelled teepee or less commonly tipi, and often called a lodge in older English writings, is a conical tent, traditionally made of animal skins upon wooden poles. Modern tepees usually have a canvas covering. A tepee is distinguished from other conical tents by the smoke flaps at the top of the structure. Historically, the tepee has been used by some Indigenous peoples of the Plains in the Great Plains and Canadian Prairies of North America, notably the seven sub-tribes of the Sioux, among the Iowa people, the Otoe and Pawnee, and among the Blackfeet, Crow , Assiniboines, Arapaho, and Plains Cree. They are also traditional west of the Rocky Mountains by tribes such as the Yakama and the Cayuse. They are still in use in many of these communities, though now primarily for ceremonial purposes rather than daily living. While Native American cultures and civilizations and First Nation band governments from other regions have used other types of dwellings (pueblos, wigwams, hogans, chickees, and longhouses), tepees are often stereotypically and incorrectly associated with all Native Americans in the United States and Aboriginal Canadians. The tepee is durable, provides warmth and comfort in winter, is cool in  the heat of summer, and is dry during heavy rains. Tepees can be disassembled and packed away quickly when people need to relocate and can be reconstructed quickly upon settling in a new area. Historically, this portability was important to Plains Indians with their at-times nomadic lifestyle. A similar structure, the "lavvu", is used by the Indigenous Sámi people of northern Europe. Etymology and nomenclature. The word "tepee" comes into English from the Lakota language. The wigwam or "wickiup", a dome-shaped shelter typically made of bark layered on a pole-structure, was also used by various tribes, especially  for hunting camps. The term "wigwam" has often been incorrectly used to refer to a conical skin tepee. The conventional translation in French and English for all indigenous dwellings at one time was "lodge", resulting in many compounds and place names such as sweatlodge, lodgepole pine, Red Lodge, and so on. Types and utility. Structure. A typical family tepee is a conical, portable structure with two adjustable smoke flaps, multiple poles (historically from long) called lodge poles. Lewis H. Morgan noted that, The frame consists of thirteen poles from fifteen to eighteen feet in length, which, after being tied together  at the small ends, are raised upright with a twist so as to cross the poles above the fastening. They are then drawn apart at the large ends and adjusted upon the ground in the rim of a circle usually ten feet in diameter. A number of untanned and tanned buffalo skins, stitched together in a form adjustable to the frame, are drawn around it and lashed together, as shown in the figure. The lower edges are secured to the ground with tent-pins. At the top there is an extra skin adjusted as a collar, so as to be  open on the windward side to facilitate the exit of the smoke. A low opening is left for a doorway, which is covered with an extra skin used as a drop. The fire-pit and arrangements for beds are the same as in the Ojibwa lodge, grass being used in the place of spruce or hemlock twigs. Lodgepole pine is the preferred wood in the Northern and Central Plains and red cedar in the Southern Plains. Tepees have a detachable cover over the structure. The cover has historically been made of buffalo hide, an optional skin or cloth lining, and  a canvas or bison calf skin door. Modern lodges are more often made of canvas. Ropes (historically raw hide) and wooden pegs are required to bind the poles, close the cover, attach the lining and door, and anchor the resulting structure to the ground. Tepees are distinguished from other tents by two crucial elements: the opening at the top and the smoke flaps, which allow the dwellers to heat themselves and cook with an open fire; and the lining that is primarily used in the winter, which insulates. Tepees were designed to be easily set up or taken down to  allow camps to be moved to follow game migrations, especially the bison. When dismantled the tepee poles were used to construct a dog- or later horse-pulled travois on which additional poles and tepee cover were placed. Tepee covers are made by sewing together strips of canvas or tanned hide and cutting out a semicircular shape from the resulting surface. Trimming this shape yields a door and the smoke flaps that allow the dwellers to control the chimney effect to expel smoke from their fires. Old style traditional linings were hides, blankets, and rectangular pieces of cloth hanging about above  the ground tied to the poles or a rope. Decoration. Historically, most tepees in a village would not be painted. Painted tepees often depicted note-worthy historical battles and often featured geometric portrayals of celestial bodies and animal designs. Sometimes tepees have been painted to depict personal experiences such as war hunting, a dream or vision. When depicting visions, "ceremonies and prayers were first offered, and then the dreamer recounted his dream to the priests and wise men of the community. Those known to be skilled painters were consulted, and the new design was made to fit anonymously within the  traditional framework of the tribe's painted tipis."
