  • Concrete Interstate Tipis of South Dakota (Constructed 1968-79) Meet the Criteria Consideration G Because of Their Exceptional Importance
    NPS Form 10-900-a OMB No. 1024-0018 United States Department of the Interior Concrete Interstate TipisPut of South Here Dakota National Park Service Multiple Property Listing Name of Property National Register of Historic Places Multiple, South Dakota Continuation Sheet County and State Section number E Page 1 E. Statement of Historic Contexts NOTE: The terms “tipi,” “tepee,” and “teepee” are used interchangeably in both historical and popular documents. For consistency, the term “tipi” will be used in this document unless an alternate spelling is quoted directly. NOTE: The interstate tipis are not true tipis. They are concrete structures that imitate lodgepoles, or the lodgepoles framing the tipi structure. The lodgepoles interlock in a similar spiral fashion, as would a real tipi. An exact imitation of tipis would also have included smoke flap poles and covering. However, they have historically been referred to as tipis. This document will continue that tradition.

As agreed with your office, we gathered information on areas managed by two agencies: the Department of the Interior’s Bureau of Land Management (BLN) and the Department of Agriculture’s Forest Service. Specifically, this report provides information on (1) legislative guidance and the agency policies governing wilderness study area management, (2) the various activities and uses occurring in the agencies’ study areas, (3) the ways these activities and uses affect the areas, and (4) agency actions to monitor and restrict these uses and to repair damage resulting from them.

    Space and Social Structure in the A.D. 13th Century Occupation of Promontory Cave 1, Utah by Courtney D. Lakevold A thesis submitted in partial fulfillment of the requirements for the degree of Master of Arts Department of Anthropology University of Alberta © Courtney D. Lakevold, 2017 ABSTRACT Promontory Cave 1, located on the north shore of Great Salt Lake in northern Utah, has yielded many extraordinary archaeological artifacts that are amazingly well-preserved. Promontory phase deposits in Cave 1 are extremely thick, and rich with perishables and other material culture. Bison bones, fur, leather and hide processing artifacts have been recovered at the site, in addition to gaming pieces, basketry, pottery, juniper bark for bedding, knife handles, ceramics and moccasins. A large central hearth area, pictograph panels, pathways and entrance and exit routes have also been identified. Bayesian modeling from AMS dates indicates a high probability that the cave was occupied for one or two human generations over a 20-50 year interval (A.D. 1240-1290). Excavations have taken place at the cave from 2011-2014 by an interdisciplinary research team with members from the University of Alberta (Institute of Prairie Archaeology), the Natural History Museum of Utah (NHMU), Oxford, the Desert Research Institute and Brigham Young University. The extraordinary preservation and narrow time frame (A.D. 1240-1290) for the occupation of Promontory Cave 1 on Great Salt Lake allow for unusual insights into the demography of its Promontory Culture inhabitants. This thesis looks at the cave as a humanly inhabited space and examines what the Promontory Culture group may have looked like in terms of population size and group composition, and how they used or organized space in the cave.

  • A Historical Note
    A Historical Note We have included the information on this page to show you the original procedure that the Sioux used to determine the proper tripod pole measurements. If you have a tipi and do not know what size it is (or if you lose this set up booklet) you would use the method explained on this page to find your exact tripod pole lengths. It is simple and it works every time. We include this page only as an interesting historical reference. You will not need to follow the instructions on this page. The complete instructions that you will follow to set up your Nomadics tipi begin on page 4. All the measurements you will need are already figured out for you starting on page 5. -4”- In order to establish the proper position and length for the door pole, start at A and walk around the edge of the tipi cover to point B. Walk toe-to-heel one foot in front of the other and count your steps from A to B. Let us say for instance that you count 30 steps from A to B. Simply divide 30 by 1/3. This gives you 10. That means that you start again at A and walk toe-to- heel around the edge of the tipi cover 10 steps, going towards B again. Stop at 10 steps and place the end of the door pole (D) at that point on the edge of the tipi cover. Your three tripod poles should now look like the drawing above. The north and south poles going side by side down the middle of the tipi cover, the door pole placed 1/3 of the way from A to B, and the door pole crossing the north and south poles at Z.
