Abstract
In early 2017, Moore Archeological Consulting, Inc. (MAC) conducted archeological monitoring of mechanical scraping at site 41LB42 located on Capers Ridge in Liberty County, Texas. This action was done to offset adverse effects associated with impending pipeline installation as part of the larger Luce Bayou Interbasin Transfer Project (LBITP), a Coastal Water Authority (CWA) infrastructure undertaking that will transport freshwater from the lower Trinity River to Lake Houston. Previously survey, testing and data recovery by MAC identified high density, high integrity finds situated on the summits of three small knolls found within 41LB42. The CWA subsequently repositioned the LBITP pipeline alignment further north, but within the site boundaries to largely avoid these archeological deposits. From February 28th to March 23rd, 2017, MAC archeologists monitored systematic removal of topsoil archeosediments at site 41LB42 within the revised pipeline alignment. A total of 3.2 acres (12,977 m3 ) and 514 linear meters (1686 ft.) by 24.4 meters (80 ft.) were excavated to subsoil at depths ranging from 25 to 250 cm. Four features were observed and documented during this work. No culturally significant finds were discovered. All materials collected and records generated have been prepared by MAC for permanent curation at Sam Houston Memorial Museum, Huntsville. It appears that the revised pipeline alignment was largely successful in avoiding and preserving high value archeosediments at 41LB42. Additional monitoring of deep excavations associated with pipeline installation are recommended. Diligent archeological monitoring is recommended for any ground disturbance in the remaining, preserved high contours areas at 41LB42.
