The earth home, in its many varieties and styles, played an important role in the development of the American Great Plains during the mid-nineteenth century. However, the lack of further study into the material culture of these homes has allowed many of these homes to be misrepresented in the historical record as temporary shelters. Not all of the earth homes constructed during this period were temporary. Further study of the materials used, the locations in which they were built, and their construction methods suggest that many of these homes were built to last. The three case studies used in this thesis represent a large number of earth homes still standing today. The findings of this study enhance the history of the region and open up new avenues for further research on earth homes as well as the possibilities and the importance of their preservation.
