ABSTRACT
The United States of America possesses an important architectural and archaeological heritage of built earth, both major monuments and traditional architecture. The vastness of the country and the differences in climate and territory greatly affect the variety of techniques used: cob, rammed earth, adobe, wattle and daub, earthen renderings, sod, turf, tabby, etc. In addition to the different constructive cultures found in the country resulting from autochthonous cultural influences (Native Americans with their cultural differences), those imported over time by the different peoples who have settled on North American territory (especially Spanish, French, English, African, Caribbean) and the transfer of knowledge in border territories (Mexico) are also reflected in the large variety of construction processes. The study of these techniques and their cultural transfer are of great interest not only to North American researchers but also to researchers in earthen architecture, earthen built heritage, or traditional architecture in general.
