Despite advocacy of landscape approaches in cultural resource management (CRM) and critiques of the site concept, CRM data collection methods in the western United States continue to focus on individual archaeological sites as units of observation, analysis, and management. The transect-recording unit (TRU) method strikes a balance between conventional site-based recording methods and site-less survey approaches by dividing survey space into a grid of uniformly sized cells for recording all cultural manifestations observed across a survey area. TRU survey generates site boundaries required by CRM regulations while retaining a fine-grained spatial framework for landscape-level research and management. This article discusses the technical requirements of the TRU system and its potential for improving landscape-level research and management. Advances in digital recording technologies and analysis techniques render the method efficient and effective in identifying cultural resource distributions and characteristics otherwise obscured by conventional approaches. The research and management potential of the TRU system is illustrated through identification and interpretation of precontact foot trails in New Mexico's Tularosa Basin. These trails are essentially invisible during pedestrian survey but are readily identifiable as linear patterns using aggregated landscape-scale TRU survey data from multiple survey projects, providing novel insight into precontact routes of movement and exchange.

This manuscript presents a novel approach to the study of contemporary material culture using digital data. Scholars interested in the materiality of past and contemporary societies have been limited to information derived from assemblages of excavated, collected, or physically observed materials; they have yet to take full advantage of large or complex digital datasets afforded by the internet. To demonstrate the power of this approach and its potential to disrupt our understanding of the material world, we present a study of an ongoing global health crisis, the COVID-19 pandemic. In particular, we focus on face-mask production during the pandemic across the United States in 2020 and 2021. Scraping information on homemade face-mask characteristics at multimonth intervals—including location and materials—we analyze the production of masks and their change over time. We demonstrate that this new methodology, coupled with a sociopolitical examination of mask use according to state policies and politicization, provides an unprecedented avenue to understand the changing distributions and social significances of material culture. Our study of mask making elucidates a clear linkage between partisan politics and decreasing disease mitigation effectiveness. We further reveal how time-averaged asssemblages drown out the political meanings of artifacts otherwise visible with finer temporal resolution.

Se presentan los resultados del recorrido de superficie realizado en la comunidad de Santo Domingo Tonaltepec en la Mixteca Alta de Oaxaca, en el que se identificaron y registraron 43 nuevos sitios arqueológicos datados a las fases Ramos (alrededor de los 300 aC hasta los 250 dC), Las Flores (aproximadamente 250-900 dC) y Natividad (aproximadamente 900-1521 dC). Estos nuevos sitios se contextualizan en el ámbito regional al relacionarlos con los sitios urbanos identificados para cada una de estas fases en los valles adyacentes de Coixtlahuaca, Nochixtlán, Tamazulapan y Teposcolula. Basados en estos datos, consideramos que Tonaltepec se encontró relativamente aislado y fuera del control de los sitios urbanos tempranos durante Ramos; que se transformó en un asentamiento fronterizo entre las entidades políticas durante la fase Las Flores; y que aprovechó los beneficios de localizarse sobre la ruta de comunicación entre importantes reinos mixtecos durante Natividad. La localización de Tonaltepec, relativamente lejos de los principales valles, pero a la vez entre ellos, le otorgó ventajas que supo aprovechar a través de la historia de desarrollo político de la región.
