The preparation of bones from jackets #8, #11, and #16, from site 41BX1239, is described in a step-by-step fashion. Recovered remains of at least 11 bones from two mammoths, Mammuthus sp., were prepared using reversible consolidants, according to methods developed at the Mammoth Site of Hot Springs, SD, Inc. Recommendations for bone treatment from other jackets recovered from the site are s given.
The Texas Department of Transportation (TxDOT), conducted National Register of Historic Places (NRHP) eligibility testing of the Cornelio Alvarez Sr. site (41SR242) as part of the State Loop (SL) 195 project (Project) (CSJ: 3632-01-001) in Starr County, Texas. Subsequent to the field investigations, SWCA Environmental Consultants (SWCA) conducted artifact analysis, reporting, and curation preparation for the multi-component historic and prehistoric site. Investigations were conducted in compliance with Section 106 of the National Historic Preservation Act (54 United State Code 30601) and the Antiquities Code of Texas (9 Natural Resources Code). The investigations assessed the site’s eligibility for listing on the NRHP (36 Code of Federal Regulations 60.4) and for designation as a State Antiquities Landmark (SAL; 13 Texas Administrative Code 26.8, 26.12). Christopher W. Ringstaff served as Principal Investigator under Texas Antiquities Permit Number 7912. TxDOT conducted the field investigations were from February 20–24, 2017, and April 10–14, 2017.
Site 41SR242 is primarily a Middle to Late Archaic site with lesser Late Prehistoric and perhaps earlier components. The open occupational site is located on an upland margin landform in a tributary valley a few miles from the Rio Grande. The investigations revealed material assemblages consisting of diffusely scattered burned rock, debitage, and lithic tools, which were predominantly recovered from a 30- to 50-cm-thick stratum of mixed artifacts. However, a few concentrations of artifacts were identified, and each location yielded isolated intact features. Formation and post-depositional processes are generally not conducive to preservation of intact archeological surfaces, patterns, or site structure. Although the overall site lacks integrity and potential data yield, isolated discrete behavioral loci are present. Therefore, site 41SR242 is recommended as eligible for the NRHP and as an SAL. This recommendation pertains to the portions of the site within the APE. The site extends beyond the APE, and the areas outside of the APE have not been evaluated.
IntroductIonWith this report, Texas Department of Transportation (TxDOT) begins a reconsideration of approaches to the evaluation and treatment of those areas where surface lithic scatters are the main constituent of the archeological record. The reconsideration was inspired by the Cuatro Vientos project in Laredo, Webb County, Texas. The project and the ideas surrounding it developed slowly. The ideas continued to evolve through discussion between SWCA Environmental Consultants (SWCA) and TxDOT as additional work on the project occurred. Because this project proceeded in an idiosyncratic fashion, some words of explanation might be helpful. The following discussion provides an account of how the project developed and where future work might be heading.
PrevIous work at cuatro vIentosBlanton and Associates (Blanton) conducted the initial survey of the project's area of potential effects (Ringstaff et al. 2004). The survey identified 14 sites. The Blanton survey report showed the local archeological record to predominantly be a messy landscape of mixed assemblages. Within this landscape were some pockets with potentially-preserved, isolable components and features. The Blanton survey report thus recommended eight of the 14 sites for additional evaluation. TxDOT, in consultation with the Texas Historical Commission, accepted those recommendations.TxDOT then tasked SWCA with developing a scope for the fieldwork under one of TxDOT's general archeological services contracts. SWCA's approach concentrated on the identification of those select areas that had a high level of integrity, with horizontal and/or vertical separation of assemblages and components (Carpenter, Houk, and Miller 2005). This integrity-focused approach has been explicitly advocated by TxDOT in the past and continues to inform TxDOT's evaluations of the effects of its projects.
IntegrIty and the evaluatIon oF south texas sItesThe integrity-focused approach can perhaps be refined, however. Two issues must be addressed. On the one hand, the archeological record of south Texas and its upland lithic scatters is not amenable to many interpretive strategies. The data from the uplands are typically of poor quality. In many places, the ground surface has remained stable or has eroded. Preservation of many types of material is poor. The same general areas have seen repeated occupation. This combination of factors has produced an archeological record that can be difficult to render meaningful. Many aspects of past human behavior and adaptations can not be inferred under these circumstances. On the other hand, the activities that occurred in these areas may have played a significant role in local adaptations. We should not be willing to treat such a large portion of the archeological record as a black box, where significant activities remain unidentified. To ignore the uplands makes an appreciation of the valley settings more difficult, since data would not be available from the upland areas for comparative analysis. Refining current approaches means splitting ...
