The Redwine site (41SM193) is a probable Middle Caddoan habitation site located on an upland terrace (Figure I) on the headwaters of Auburn Creek, a small tributary of the Sabine River in central Smith County; the Angelina River drainage basin begins about 1.5 km to the south of the site. Auburn Creek is about 100 meters to the north of the site. The Sabine River lies approximately 24 km to the north. Soils on the Redwine site are Bowie fine sandy loam. The site was discovered in the early 1960s by Sam Whlteside an avocational archaeologist who lived in the Tyler area. His work consisted of trenching, and he located and excavated several burials and a small house mound. In an attempt to relocate the site limited controlled excavations were undertaken in 1995 by the authors, under the direction of Dr. John Keller of Southern Archaeological Consultants, Inc. We hoped to gain enough information about the size, age, and integrity of the Redwine site to apply for legal designation and protection under the Antiquities Code of Texas. After confirming that the Redwine site contained important archaeological information, an application for State Archeological Landmark (SAL) designation was made in 1996, and in July 1996, the Redwine site was officially designated an SAL by the Texas Historical Commission, the first SAL in Smith County. This paper describes our findings, and discusses the artifacts and plant and animal remains recovered during the work. We also provide information on the 1960s excavations of a small house mound at the site, along with the grave goods recovered by Sam Whiteside from the four Redwine site burials.
