In this article, we present a unique case study in Indianapolis, Indiana, where cultural resource management (CRM) archaeologists, alongside various university archaeologists, tested the use of SfM photogrammetry to effectively replace traditional archaeological methods of mapping and documentation during the excavation of over 500 historic burials. This project was designed with the intention of using SfM photogrammetry for 3D mapping and documentation from its inception, implementing formal procedures and protocols for data collection creating a standard workflow. To our knowledge, this is the first integrated use of SfM at this scale on an archaeological project in Indiana. By the close of fieldwork, over 300 burials had been digitally recorded, and measurable 3D models were generated. We found that the standard photogrammetry workflow implemented for single context excavation was largely successful. First, we outline the data collection process for 3D mapping of single-context excavations at Bethel Cemetery. This is followed by a description of the problems encountered during data collection and the ways the photogrammetry team adapted to variability in field environments for photocapture. Finally, we recommend the adoption of these methods by practitioners/academics as standard practice in the archaeological excavation of human remains.

In this article, we present the most significant results of the Monte Albán Geophysical Archaeology Project. Using ground-penetrating radar, gradiometry, and electrical resistance, we carried out a systematic survey of the site's Main Plaza to identify buried prehispanic features that might shed light on Monte Albán's early history. The most important discoveries include three buried structures dating between the Danibaan (500–300 BC) and Nisa phases (100 BC–AD 100). We argue that the largest structure, measuring 18 × 18 m, was probably a temple platform and that all three of the structures were razed and buried by the end of the Nisa phase at the latest. Furthermore, we contend that these events were part of a major renovation and expansion of the site's Main Plaza that occurred during a pivotal period of dramatic sociopolitical transformation in the Zapotec capital.

During an archaeological survey in the municipality of San Pedro Mártir Quiechapa, Oaxaca, Mexico, archaeologists from the Proyecto Arqueológico de Quiechapa (PAQuie) encountered and documented a number of carved stone elements. Of particular interest are the 30 representations of ballcourts carved into natural rock outcrops at two sites in the region. This is the highest density in which this type of ballcourt representation occurs throughout Mesoamerica. After their initial discovery, members of PAQuie documented the carved stone ballcourts using structure-from-motion (SfM) photogrammetry, a quick and affordable technique to collect 3D spatial, quantitative, and visual data of stone carvings. In this article, I report on the carved stone ballcourt representations documented in the Quiechapa region and offer some preliminary interpretations. I first provide some description of the broader archaeological context in which the carvings were found. Then I describe the methods used to record the stone carvings, followed by a presentation of the data. Finally, in dialogue with extant literature, I explore some possibilities as to why these carved stone ballcourt representations were created, how they may have been used, and what they may symbolize.
