scholarly journals Pharr-Reynosa International Bridge: Continued Archeological and Historical Research at El Capote Ranch Community, Hidalgo County, Texas

Phase II cultural resources investigations for the Pharr-Reynosa International Bridge currently under construction in Hidalgo County, Texas, were conducted by Prewitt and Associates, Inc. in September 1993 and June 1994. The work included additional survey and documentation of seven historic sites, testing and evaluation of three sites, archival and oral history research on the former Hispanic community of EI Capote, and collection of additional geoarcheological data. The seven historic sites (4IHG162-41HG168) represent former nineteenth- and twentieth-century house sites within EI Capote. Due to a lack of integrity, it is recommended that all seven sites be considered ineligible for listing on the National Register of Historic Places. Three other probable historic sites (Garza Ranch No.2, a segment of the Old Military Road, and the de la Viila Ranch) are located outside the area of potential effects. These were not recorded, but their locations are noted. Also outside the area of potential effects, a historic house site (4IHG 169) contains the only known standing dwelling associated with nineteenth-century EI Capote. Mechanical and hand excavations of the historic components at 41HG153 and 41HG158 revealed severe disturbances and lack of intact features. It is recommended that these site~ be considered ineligible for listing on the National Register. Surface and subsurface search for additional evidence of prehistoric occupations at 41HG153 yielded one artifact. It is recommended that the prehistoric component at 41HG153 also be considered ineligible for listing on the National Register. Mapping and recording of features at a historic brick factory confirmed the site's high archeological integrity. Site 41HG156 is the only Ranching Period brick kiln known in the Lower Rio Grande Valley of Texas. It is recommended that it be considered eligible for listing on the National Register.

Archeological, archival, and geomorphologic investigations were conducted for the proposed Pharr-Reynosa International Bridge Project in Hidalgo County, Texas, by Prewitt and Associates, Inc. from October 12-27, 1992. The purposes of these investigations were to locate and record any cultural resources within the project area, determine their eligibility for listing on the National Register of Historic Places and designation as State Archeological Landmarks, and to provide an overview of the Holocene geomorphic history of the project area. The geomorphic history of the project area suggests that the Rio Grande has experienced continuous channel aggradation from the end of the Pleistocene to ca. 1000 B.P. Climatic changes and diminishing sediment loads led to channel incision around 1000 B.P., forming a low late Holocene terrace and resulting in increased sinuosity and a decreased channel width-to-depth ratio. The investigations included a stratified sample survey of approximately 162 hectares (400 acres) and the excavation of 16 backhoe trenches and 14 shovel tests. A total of 10 sites, consisting of 10 historic and 2 prehistoric components, were documented. Six standing architectural properties, each consisting of a structure or groups of structures, also were documented. Four of the sites (41HG153, 41HG155, 41HG156, and 41HG158) are considered to be potentially eligible for listing on the National Register of Historic Places and for designation as State Archeological Landmarks. Two of the architectural properties - the Carmichael and Sorenson farmsteads - also may be eligible for listing on the National Register. The four potentially eligible sites consist of four historic and two prehistoric components. The historic components date from the Texas Republic period to the early twentieth century, representing the establishment and development of the EI Capote Ranch community. The two prehistoric components (41HG153 and 41HG158), of which only 41HG153 is potentially eligible, represent Late Prehistoric and unknown prehistoric components, respectively.

Major citrus blackfly (Aleurocanthus woglumi) outbreaks occur periodically in the Lower Rio Grande Valley (LRGV) of Texas, causing a reduction in citrus (Citrus sp.) tree yields. This research reports on the integration of airborne color-infrared (ACIR) imagery and geographic information system (GIS) technology for mapping citrus blackfly outbreaks appearing in this area in separate years. For this study, the 1993 and 2002 citrus blackfly infestations were mapped and compared. Outbreaks did not appear at the same sites for 1993 and 2002. In 1993, infestations occurred in the southern part of Hidalgo and Cameron counties compared with outbreaks primarily appearing in the western portion of Hidalgo County in 2002. For both years, Hidalgo County was affected more than the other citrus producing counties in the LRGV. This study demonstrated airborne remote sensing imagery integrated with GIS technology could be used to develop maps for comparing citrus blackfly infestations appearing in separate years.
