Golden Triangle Storage Project at Spindletop Oil Field, Beaumont, Texas

AGL Resources

WSA is conducting ongoing archaeological investigations of the portion of the Golden Triangle Storage Project that is located within the boundary of the Lucas Gusher/Spindletop Oil Field, a National Register of Historic Places listed property and a National Historic Landmark located near Beaumont, Jefferson County, Texas. The need for cultural resources investigations for the Project is the result of GTS seeking authorization from the Federal Energy Regulatory Commission (FERC) to construct and operate the project. Because the project is located within the NHL, the purpose of the initial cultural resources investigations was to identify specific historically significant cultural resources via archival research and an archaeological survey. As a result WSA identified 11 archaeologically sensitive zones. Data Recovery of the Derrick Yard (Zone 1) took place in June to July of 2008. Numerous features including derrick platforms, storage tanks, remnants of a boiler house, and well heads relating to the First and Second Oil Boom Periods (1901-1908 and 1925-1936) of the Spindletop Oil Field have been identified. Consultation with AGL and the Texas SHPO is ongoing in order to mitigate plans for the other zones.

Chickasaw National Recreation Area, Sulphur, Oklahoma

Bureau of Reclamation and National Park Service

WSA conducted an intensive archaeological survey with approximately 200 shovel tests of a portion of the Chickasaw National Recreation Area (NRA), within the Platt Historic District, adjacent to Veterans Lake Dam, south of Sulphur, Oklahoma. The survey was conducted on behalf of the Bureau of Reclamation (BOR) and the National Park Service (NPS) under Section 106 in advance of dam rehabilitation. The Chickasaw NRA is the historic settlement area of the displaced Chickasaw and Choctaw Indians who were relegated to Oklahoma in the early 1800’s. The U.S. Government purchased 640 acres from the Chickasaw and Choctaw creating the Sulphur Springs Reservation in 1902 which through time became the NRA. The Platt Historic District is located within the northern end of the Chickasaw NRA. The district relates primarily to historic landscape resources from 1933 to 1940. During this period, NPS professionals planned and designed an infrastructure that included spring pavilions, campgrounds, picnic areas, dams and waterfalls and was constructed by the Civilian Conservation Corps (CCC). WSA crews camped within the extremely well crafted campgrounds and beautiful park while conducting the survey.

Rio Grande Canalization Project, New Mexico and Texas

United States Section of the International Boundary and Water Commission (USIBWC) and CH2M Hill

WSA conducted archaeological investigations for the proposed levee construction along the Rio Grande on behalf of CH2M Hill and the United States Section of the International Boundary and Water Commission (USIBWC). The USIBWC intends to rehabilitate the Rio Grande Canalization Project (RGCP) flood control system. The RGCP consisted of a narrow river corridor that extended 105.4 miles along the Rio Grande. WSA conducted archival research in both Texas and New Mexico to obtain a current list of cultural (archaeological, historical, and prehistoric) resources within the project area. Archaeological investigations included backhoe trenching and shovel testing in areas of proposed levee improvements. Thirteen previously identified archaeological sites were revisited. Two newly identified prehistoric sites in New Mexico were recommended as eligible to the NRHP. Both sites may represent well preserved Eastern Jornada Mogollon occupation sites.

UNEV Pipeline Project, Nevada & Utah

Holly Corporation

As part of the UNEV Pipeline Project for Holly Energy, WSA surveyed over 500 miles of proposed pipeline corridor and ancillary facilities between Salt Lake City, Utah and Las Vegas, Nevada. Over 300 historic and prehistoric sites were identified and recorded during the survey process. The subsequent 6-volume, 5000-page Class III BLM survey report included a geomorphological analysis of the project areas, ethnographical summary of Great Basin cultures, descriptions and assessment of each site within the project area, lithic and groundstone analysis including extensive obsidian hydration and sourcing analysis, and over 500 illustrations and maps. WSA prepared two treatment plans (for Nevada and Utah) that outline a program to guide the mitigation phase for cultural resources on the UNEV project. Strategies proposed for mitigating the adverse effects of the pipeline construction project to NRHP-eligible sites include: phased data recovery, mitigative documentation, avoidance, construction monitoring, and off-site mitigation such as geoarchaeological assessment and additional obsidian hydration and sourcing. The data recovery and monitoring of the work, as well as analysis and reporting, will continue into 2011.

El Paso-to-Phoenix Expansion Project (EPX), Arizona, New Mexico & Texas

Kinder Morgan Energy Partners

WSA conducted record searches, agency and Native American coordination and field surveys, and prepared Class III Survey Reports, Agreement Documents, and an Historic Property Treatment Plan to assist Kinder Morgan Energy Partners with the construction of an expansion pipeline from El Paso to Phoenix (EPX). The project area spanned 2,914 acres and 98 linear miles - within which WSA identified and recommended treatment for 41 cultural properties. WSA then conducted phased data recovery at 5 sites over 6 months, and completed mitigative documentation at 8 additional sites. WSA recorded over 250 prehistoric habitation features and collected, analyzed, and curated thousands of artifacts. All archaeological excavations were completed in advance of pipeline construction, at which time WSA monitored construction activities within culturally sensitive areas. A multi-volume report is in preparation, to be completed in early 2010.
