Recovering archaeological and paleontological remains involves the systematic destruction of the stratigraphic record, which is essential for reconstructing processes of site formation. Therefore, once excavation is finished the details are no longer visible. This may impede the re-analysis of the data in their original context when it is time to test new hypotheses. Often reinterpretation of a site has to be accomplished through a re-analysis of reports, maps and photographs created during the initial excavation, most of which are always lack detail and are conducive to misinterpretations. Geospatial technologies provide a way of recording information and updating it. One of such technologies is Structure from Motion (SfM), which is a method that uses multiple photographs of archaeologic or paleontological localities to create an interactive 3D representation of the localities. This paper discusses the geomorphology and soil stratigraphy of the Alva, Buffalo, and Eagle City mammoth localities using SfM as part of a broader project that aims at reconstructing of Late Pleistocene Proboscidean environments. The information gained from this type of analysis can then be used for future analysis, or re-analysis of the site, as well as for predicting localities with similar records in the same area.
